Personally, I prefer programming in Qt versus GTK. Also, I think GTK is losing developer's mind-share and Qt is moving forward faster, is targeting mobile platforms, is quite active, backed by a company, etc., etc. This kind of things are very important because some of us would like to make a living out of these things!

As someone who would like to create a commercial application for desktop, I really appreciate that at least the UI frameworks for Windows and OSX are quite stable.
