In function:
menu_item = gtk_radio_menu_item_new_with_label (NULL, "Apples");
gtk_menu_append (GTK_MENU (menu), menu_item);
gtk_object_set_data (GTK_OBJECT (dialog), "radio_button_apples", menu_item);
gtk_widget_show (menu_item);

menu_item = gtk_radio_menu_item_new_with_label (
gtk_radio_menu_item_group (GTK_RADIO_MENU_ITEM (menu_item)), "Oranges");
gtk_menu_append (GTK_MENU (menu), menu_item);
gtk_object_set_data (GTK_OBJECT (dialog), "radio_button_oranges", menu_item);
gtk_widget_show (menu_item);

In callback:
button = (GtkWidget *) gtk_object_get_data (GTK_OBJECT (dialog), "radio_button_apples");
if (GTK_TOGGLE_BUTTON (button)->active == TRUE) do_apples (data);
etc...
