No! That isn't correct. When you create a window it has a ref count of
1, but that count is owned by GTK. You can't call unref(), you must
call gtk_object_destroy(), which will cause GTK to drop its count. If
you can unref() then GTK will segfault eventually.

In the example code I think gtk_object_destroy() on the window will
free everything, though I don't understand why the extra ref on the
child button is used, since containers ref their children anyway.
