You should use gtk_widget_set_parent(), which takes care of that, and
also maintains some invariants that the widget system expects.

Child widgets are automatically realized when they need to be; you don't
need to call gtk_widget_realize() on them explicitly.

However, if your subwidgets are not children of widget->window, you
should call gtk_widget_set_parent_window() on them.

See the widgets that come with GTK+; there are many examples of how to
do this kind of thing.
