Check it out, while they still use their own libs,
this nifty app can apparently draw GTK2 widgits using whatever QT style you are using. The example shows KDE running the thin-keramik style with gedit and The GIMP themed and actually looking like they match.
Very cool, now if I can just get it to compile

EDIT: to get it to compile I have to make a symlink for /usr/lib/qt-3.1 to /usr/lib/qt3
