This is a matter of personal preferance and what you wish to do. Obviously if your going for the windows platform you are going to work with Windows Frameworks/Libraries (MFC, .NET, etc)

The Linux platform you will lean more to GTK+.

Furthermore, how high of a level do you want to work on? C++ is more a low level language then, say, C#. In so far as the Adobe products are concerned, if I had to guess, I would say they were created using VC++ but that is strictly a guess.
