You can read about this here

Another way would be to render the main window on the overlay and apply some image filters on the overlay image.. Filters can be searched in Qt Labs if i remember right

Do you mean this?

You can paint picture, but you can't hide controls, so you need create toplevel qwidget (layer) what hide other widgets. But i think you don't need image filter for this simple job, just use transparent.

Sort of... What I meant was, if you apply effects/filters to the overlay layer, you can get some fancy output...u can appply effects like blur, ripple, swirl etc...
