Using Gdk::Window::add_filter [1]. Gobby used to use it to wait for 
network events with WSAAsyncSelect, this might be helpful as an example [2].

Also note that a Gtk::Window's Gdk::Window does only exist after 
realization of the widget, use signal_realize() to wait for that to 
happen instead of accessing it directly after construction.
