Do all gui toolkits suck?

After messing around with wxwidgets, qt, and gtk+, I'm under this impression. Do they all suck or am I just not reading the docs correctly

Qt is, without a doubt, the best GUI toolkit I've ever used. It also has some of the best documentation I've ever encountered.

The one major, crushing con is that it pretty much hijacks your entire development process - especially when you're working on a windoz computer - because it has to add an extra "moc" step where it preprocesses your code.
