Create a window, without border, and without title bar; and draw them 
yourself?
Ok, yes that's ugly, because those windows will then look and behave 
different (depending on how well you emulate the windowmanager (or how 
bad you emulate it).

I don't know if Microsoft does this, but in visual studio floating 
windows have a different border color, different looking icons, and no 
shadow....
