GTK doesn't much care about integrating into a Qt environment and doesn't really implement anything to make that work besides in some cases implementing the same Freedesktop standards. Even for basic things like the look of widgets you need a style that has implementations for GTK - there is no compatibility layer to use Qt styles. Gnomies in general don't care about anything outside their world.
The other way around is a bit better, e.g. there is QGtkStyle but AFAIK it is stuck at GTK2 and does not support using GTK3 styles. Still, behavior between GTK and Qt applications is very noticeably different.
It would be great if there was a shared ABI applications could use but GUI toolkits are too complicated for this to be feasible.
