the Gdk window is the one for which you can get a position.
try this:

   $win = new Gtk::Window 'toplevel';
   $win->add_events ( 'button-press-mask' );
   $win->signal_connect ( button_press_event => sub {
                  use Data::Dumper;
                  print Dumper( [ $win->window->get_position ] );
                  1;
                  } );
   $win->signal_connect ( delete_event => sub { Gtk->main_quit; 1 } );
   $win->show;
   Gtk->main;

move the window and click in it, then do it again.  looks like the root 
window coordinates of the Gdk window.  for child windows it tells you 
the position relative to the upper left corner of the parent.
