That would work with xfwm4 either way. Transients for groups get hidden 
once all windows of the same group have been hidden. This way, if you 
have two parent windows, the utility windows will hide once both parent 
windows are hidden.

gtk+ uses gdk which has:


void          gdk_window_set_transient_for (GdkWindow       *window,
					    GdkWindow       *parent);

and

GdkWindow *gdk_get_default_root_window (void);

or

GdkWindow *  gdk_screen_get_root_window       (GdkScreen   *screen);

So it doable in gtk+/gdk (I should have an example available somewhere 
if needed, but it would require some research :) ).
