I am not a fan of QT, this is just compared to many toolkits out there (lets say fox-toolkit, qt, win32, ...) GTK performs terrible due to its design.
There exist several papers from Gnome hackers about this problems and suggestions for a fix. I really hope that things will become better in GTK-3.0.
