Desktop widgets a la SuperKaramba/Opera Widgets

Hi there!
I am looking for way to put my application windows at fixed position on the background of my desktop. I use Qt 4 and KDE. I would like to bypass SuperKaramba, and use just Qt. I tried with different Qt window styles, and can't get it to work.

What I want is window that always stays below other and is not managable by window manager.

Any suggestions?

create a QMainWindow with flag 'Qt::FramelessWindowHint'

size and position can be controled by methods resize and move.

best regards,
jh
