Maybe this is your problem:

	Gtk::Label testLabel1("Test label 1");
	Gtk::Label testLabel2("Test label 2");
	Gtk::Label testLabel3("Test label 3");
	
	append_page(testLabel1, "Page 1");
	append_page(testLabel2, "Page 2");
	append_page(testLabel3, "Page 3");

Those Gtk::Label instances are automatically destroyed as soon as that
method ends. You might use class members instead, or Gtk::manage(new
Gtk::Label("something")).
