GUI application design toolkits. which one?
Can someone point me into the right direction when it comes to GUI application programming? I mainly work in Linux, but I would like my apps to be easily portable to FreeBSD and Windows XP.
Is wxwidgets (gtk+) the best option? How do Qt and Glade compare? Are there any other toolkits?
Note: Mention anything, but I want to work in C and C++.
