Yes, it is possible. With boxes the methods pack_start and pack_end
are preferred. Remember you should show the widget after add it to the
box:

builder.get_object('vbox1').pack_start(mywidget)
mywidget.show()

If your widget is composed of multiple sub widgets, you should use:

mywidget.show_all()
