Advice for C++ GUI programming

I highly recommend the use of the Qt Libraries for several reasons:

1. The Framework is freely available for Windows, Linux, MacOS X, and a couple of mobile systems. Since version 4.5 the license is LGPL, which basically means that you can use Qt even in commercial applications.
2. The design of Qt is out-standing, e.g. they use modern design patterns and a very consistent interface design (I don't know many other libraries that use object-oriented ideas in such perfection). Using Qt is the same as using Boost: it will improve your own programming skills, because they use such beautiful concepts!
3. They are bloody fast, for instance in rendering (due to the different back-end for OpenGL, DirectX, etc.). Just have a look on this video and you see what can easily be done with Qt but is hard to achieve with native Windows, Mac, or Linux programming.
4. They have a really great documentation, with tons of tutorials and a very good reference. You can start learning Qt easily with the given docs! The documentation is also available online, so have a look and see by yourself.
5. As mentioned before, Qt is cross-platform; you have one source-base that works on all the important operating systems. Why will you limit yourself to Windows, when you can also have Mac and Linux "for free"?
6. Qt is so much more than "just" the user interface; they also offer network and database functionality, OpenGL bindings, a full-working web-browser control (based on WebKit), a multimedia playback library, and much much much more.

Honestly, I wasted a couple of years by developing software natively for Windows, while I could have been so much more productive.

For C++ you have two choices, Native or Managed.

For native development, my team (at Microsoft, in Windows) uses the Windows Template Library. It works very well for us.

You should learn the basics of Win32 and how Windowing works. The canonical tome is Programming Windows®

For Managed development you can use C++ with Windows Forms. However, windows forms has been supplanted by Windows Presentation Foundation (WPF).

• This tutorial is useful
• You can use Visual C++ 2008 Express Edition for your tools (they are free).

My best advice for Windows C++ GUI programming is don't do Windows C++ GUI programming.

I realize that is an extremely uninformative/smartass response if it's not qualified, so I'll note that you don't state that you need to do C++ Windows GUI programming, but that you "Would like to get into Windows GUI apps." If that is the case, and you don't have a very specific reason to use C++ (i.e. gigantic existing legacy codebase written in MFC or a bunch of C++ code that you want to build a front-end for but would be a pain to expose to .NET code), then it is going to be a lot easier and more productive to go the .NET route and start learning Windows Forms or better yet WPF using C# or another .NET language of your choice.

If you do need to go C++, then I would second the recommendations for 3rd party toolkits like Qt or wxWidgets, as the state of C/C++ GUI programming tools from Microsoft is now abysmal.
