You have to walk up the window tree (X windows, not GTK windows) using
XQueryTree() in a loop till you find the window whose parent is the root 
window.  This will be the Window Manager window.  Grab the window attributes 
for this window (XGetWindowAttributes()).  Then you do an XTranslateCoords() 
between this window and your widgets window.  The offset values returned from 
XTranslateCoords() should be added to the position of the WM windows x,y 
coordinates to position your window.

To my knowledge there isn't any way to do this from GTK/GDK.  I looked, but
there weren't any routines that would translate the coordinates or to query
the parent window or the children of a window.  I probably just missed them.
