Just an example:

   GtkActionGroup* action_group;
   GtkUIManager*   ui_mngr;
   GError*         error = NULL;

    gchar ui_info[] =  ""
        "<ui>"
        "  <menubar>"
        "    <menu action='MenuFile'>"
        "      <menuitem action='New' />"
        "      <menuitem action='Open' />"
        "    </menu>"
        "    <menu action='MenuEdit'>"
        "      <menuitem action='Undo' />"
        "      <menuitem action='Redo' />"
        "    </menu>"
        "  </menubar>"
        "</ui>";

    gtk_init(&argc, &argv);

    window = gtk_window_new(GTK_WINDOW_TOPLEVEL);

    action_group = gtk_action_group_new(NULL);
    gtk_action_group_add_action(action_group,
                                gtk_action_new("MenuFile", "_File",
                                               NULL, NULL));

    gtk_action_group_add_action(action_group,
                                gtk_action_new("New", NULL,
                                               NULL, GTK_STOCK_NEW)); 
    gtk_action_group_add_action(action_group, 
				gtk_action_new("Open", NULL,
                                               NULL, GTK_STOCK_OPEN));

    gtk_action_group_add_action(action_group,
                                gtk_action_new("MenuEdit", "_Edit",
                                               NULL, NULL));

    gtk_action_group_add_action(action_group,
                                gtk_action_new("Undo", NULL,
                                               NULL, GTK_STOCK_UNDO));

    gtk_action_group_add_action(action_group,
                                gtk_action_new("Redo", NULL,
                                               NULL, GTK_STOCK_REDO));

    ui_mngr = gtk_ui_manager_new();
    gtk_ui_manager_insert_action_group(ui_mngr, action_group, 0);
    gtk_ui_manager_add_ui_from_string(ui_mngr, ui_info,
                                      strlen(ui_info), &error);

    if (error)
        g_error(error->message);

     /* ... */

    gtk_box_pack_start(GTK_BOX(vbox),
                       gtk_ui_manager_get_widget(ui_mngr, "/menubar"),
                       FALSE, FALSE, 0);
