Well he should not be doing a GUI in the traditional sense, we are pretty sure from the full discussion that he should be using a web interface and whatever language he uses would just be server side.
Python will do fat GUI on the desktop just fine, it's actually well known for that and will even work with the Windows toolset via IronPython. But that's not what I would recommend here.
And that is why I don't do programming, don't know about this stuff. Might have to check out IronPython.

@scottalanmiller -- You call PHP not a modern language? What makes a language modern or not?
How do you determine the "best language" for a project? Anything you can do in one programming language can be done in another.

i just took a look on Qt Designer, it looks good, anyone use it before??
Use this: http://learnpythonthehardway.org/
I don't make a lot of suggestions here as this is mostly a learning experience but I know a lot of coders who swear by it. True to its name it's not a quick and dirty style guide. This is if you want to learn python the right way.

I wouldn't, it's just an example of the flexibility. Python + Qt is generally way better.

PHP is old in age and in design. It's not bad, but it is a "good old way" language. It is very straightforward, but is not expressive.

I would be interested in hearing more about that in another thread at some point as I'm trying to hook a Pi up to some sensors in my off time... were they i2C sensors?

Python isn't the "coolest" language, it has been around long enough to be "old and boring."
But if you read my stuff, I push it hard as the best "first" language for people to learn. It is advanced, mature, broadly available, reasonably fast and very rich in features.It is indeed fully portable, as much as any language is. And it has powerful frameworks like Django, too.
Python is an excellent choice. It is in the same family of modern languages like Ruby, JavaScript and Go.
so what is the coolest language i can learn ?? knowing that my need is the develop GUI application that can connect with database (entreprise application)
what fascinate me about python is the majority of powerful hacking tools are developed using this language like metasploit
-
Python and Ruby are two good places to start.
I have heard that Shoes works well for getting Ruby apps to work with a GUI, but I don't have any experience with it myself.

The sensors were just hooked up via digital io pins. I had a couple LED blocks hooked up via the i2c bus tho. I did all the python code with nano, it's really kinda basic stuff. Proximity sensor, temp and pressure sensor, and a couple LED 8x16 LED blocks. I really just wanted to play around and see what I could do with it, turns out interacting with sensors is quite easy.

That's tough, of course. And that is not completely true, but mostly it is. Some things, like accessing the UNIX system calls requires C, or talking to Windows API requires either C++ or the CLR. Or running across different platforms.
But different languages are expressive in different ways. Ruby is very expressive for making web interfaces. You write a lot less and get a lot more.
Scala is very good at being thread safe. Doing the same thing in JavaScript would be, effectively, impossible.
But some high level things to consider when choosing a language:
- Performance of the developer. This is probably the top concern. Working in Ruby you can do in a day when you could not do in C in a month.
- Expressiveness. This is difficult to qualify, but the more expressive a language the faster than you can work and the more clearly you can work. It makes you productive while reducing errors.
- Language architecture. Does it work in a way that is sensible for the application at hand?
- Frameworks. Choosing a language is often done based on the framework desired or available. For example, if you want to use Rails, you have to use Ruby. If you want to use Meteor, you have to use JavaScript. Frameworks often drive this decision.
- Deployment options. In a world of PaaS, containers and the like, choosing a language with broad support (by Google Railyard, Joyent, OpenShift, Elastic Beanstalk) is important. It used to be just "avoid MS tools to avoid MS lock in", but today it is far bigger as a bad language choice can not just mean investing in MS but might be "running your own servers instead of going hosted." You rarely want your language choice to determine your entire IT strategy.
- Cost. Most languages today are free. But not all. And some are free but have no available tooling.
- Support. VB.NET might be a serviceable language on its own, but no good developers will talk to you if you use it. You'll never hire support in the future or you will pay a premium as everyone willing to keep working with it knows that they have you trapped. Use a language that is able to be supported by programming professionals.
- Forward looking rather than technical debt. Similar to the support point. You want a language with a growing, vibrant ecosystem for advice, tooling, advancements, a future, etc. For example, that PHP 7 has just released means that people using PHP suddenly got a "free" 50% performance leap just for having chosen PHP. VB doesn't get leaps like that.

My dad does Python sensor programming, too.

Generally much farther down on the list is language performance. Ruby is dog slow, in general. Java is screaming fast. But language speed is one of those SMB mistakes that, like many things, people get bogged down worrying about language performance like it was 1982. But computers are so fast today that it is very, very rare that language performance is a major factor. How an application will scale IS a factor, but rarely the language speed itself.
For example, Spiceworks has huge performance issues AND uses Ruby (the slowest modern language.) But their issues are not at all from Ruby itself, but from other design issues (blocking design, for example.) They could have designed around that, gone non-blocking, not used a relational database, etc. and changed the performance dramatically.

There are many. Often the coolest are ones you don't learn casually (Haskell, F#, OCaml, Erlang, Clojure, Scala) as they are different types of languages completely and the learning curve would be absolutely brutal.
But of super modern, super "hip" languages that are broadly usable for many purposes but are actually usable by normal people look at Google's new Go Language, JavaScript on Node.js, Python and Ruby. That's a good starting point.

By and large, I agree with your last couple of posts about my question. It also comes down to the developer's familiarity with libraries within the language. I can write my app in PHP, and then use a database library that works with MySQL, Postgres, SQL, and a myriad of others without having to physically hand code for each type of database instance. There's no sense in the developer having to recreate the wheel for each application
If I were to use say.... Node or Meteor, I have no idea how to connect those to a database of any kind, so I'd have to learn those languages at the same time as I develop the application, slowing me down.

Seems like a good reason to keep using PHP to me. 8-)

8-)Familiarity is certainly a factor. But I think that it is often overrated. Learning a new framework does take time, best not to do that fresh for every project. But often a project is either really large and the time to learn a new language isn't a major portion of it or people tend to do very similar projects over and over again and learning a good way to do that particular project is well worth it.
In all cases (or nearly so) learning the language is pretty trivial. It's learning the framework that takes the big effort. Moving from one PHP framework to another may easily take as much effort as moving from PHP with Cake to Ruby on Rails.

@scottalanmiller -- It seems I missed one of your comments about PHP not being an expressive language... Can you give me an example of one that is (I'm just curious as to what you mean by that).

Ruby is considered to be on the very expressive side. It is "easier to write ideas" and, more importantly, "easier to read intent."

That free book on Functional Python is just begging for some experimentation there.
