Qt is really great. I also highly recommend that you look at Qt Creator which is
included in the SDK. Although I'm a long time Vim user, I really found this IDE
to be extremely simple and efficient. The GUI interface designer is also
directly integrated into Qt Creator.

Threading is really intuitive in Qt to me. Just extend QThread and implement
run(), done (well, almost ;).

About "skinning":

"The concepts, terminology, and syntax of Qt Style Sheets are heavily inspired
by HTML Cascading Style Sheets (CSS) but adapted to the world of widgets"

Gabriel already mentioned some pros and cons, but if that matters to you, Qt
provides quite amazing portability to other operating systems. I used it to
develop a win32 app for one my of customer, almost only working on Linux.

I really don't think there's such a high entry to the learning curve. It's all
plain C++, and the specific signal/slot syntax is intuitive.

Qt is not such a world apart IMO. I've used Gtk a lot, and I really like it too,
but I was amazed about how productive I got as soon as I started using Qt.

Hope that helps,
