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 (http://www.qtsoftware.com/products/appdev/add-on-products/catalog/4/Utilities/qtimagefilters)?

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...
