KDE4 and visual issues

I’ve installed openSuSE 11.0 from dvd with KDE3 desktop.
Now I’m adapting to KDE4 - the problem is that qt3 applications looks as in KDE3 and it is ugly (I need amarok 1.x).
Is there a plugin like KDE4/GTK that will make qt3 apps look like KDE4?
Also why yast control center main window is still in qt3, meanwhile all modules uses qt4 already?
