Qt also comes with extremely good documentation and the developers  
are very responsive. It also runs on OS X, if that is an issue, GTK  
only runs via X11 on OS X, which isn't very helpful for end users.  
The Qt API is very well organized too. I don't know if the same is  
true for GTK, but I found Qt extremely comfortable to work with.

There is Gtkmm, a C++ wrapper for Gtk, but I don't know if it is up  
to date, for a while it lagged behind.
