Something like this might work:

GdkWindow *window = gdk_window_lookup(xid);
GtkWidget *widget = gdk_window_get_user_data(window);

Of course that only works if 'xid' corresponds to a GtkWindow that you 
yourself have created *in the same application* that you call this from. 
 You can't use this, for example, to get a GtkWidget created in another 
application -- there's no way to do that.
