Why you should choose Qt? Because you could make, sugar sweet. It means creating a great user experience with user interface (UI) design. In addition, it brings you to new paradigms for portable UI’s. Go Qt!
I use Qt with some reasons. I am KDE addict, but it is not only reason making me use Qt. I use Qt because it can deploy everywhere. It is C++ toolkit, so should have mastered C++ (or Java) at first, even one code. Try to learn Qt Nokia development framework, build small application soon, and feel better after that. Qt, for the future.
