Yes, QT is in my opinion quite mature and well optimized, but well ...
expensive as hell if you don't do GPL'ed stuff.
Some time ago I did some tests against QT-3.? and it was surprisingly
fast, what I've heard QT-4 is again 20% faster.

I don't know how much Java is suited for your task, but some
benchmarks I did also showed very good UI performance for applications
writting using Java/Swing.
Fox is also very fast, but looks quite old: http://fox-toolkit.org/

Well I don't like both for application development, maybe because my
home-language is java ;)
But to be honest I guess its way better (also for the generated code)
to have OO concepts in the language itself, than to emulate it like
GLib does.
