Best Language/Tool To Develop GUI on Windows

Question

I reviewed the answers provided to the "GUI Programming APIs" post and wondering if these answers still apply.
http://stackoverflow.com/questions/610/gui-programming-apis

Specifically from that thread it appears that QT is the one that was most referenced with wxWidgets and Shoes a close second and third.

I just wanted to make sure that a definitive winner has not emerged in the past 6 months since that question was posted.

I am constrained to target OpenSource and Freeware solutions, so I will strongly lean that way.

Thanks for any feedback and insights. I've got a little experience with Perl, C++, and VB.

Answer 1

QT is still one of if not the most popular open source GUI programming API right now because it can target all the major platforms (Linux, OS X, and Windows). I don't think the results of that question have changed much if at all in the last 6 months.

Answer 2

+1 on Qt.
