Just remember,  only put gtk_main() once in your application and put it in the
main().
It is very very complicate to put multi gtk_main()  in an application (at least I
do not know how to do it), especially do not put it in some unimportant functions.

To achieve your purpose, you can write a standard warning message dialog by your
own hand, such as
Messagebox(title, text,type).
And use gtk_widget_show() to show it each time when you need it.  Never put
gtk_main() in that, since you already put it in the main();

So the function will be:
run_dialog()
{
      <create dialog with callbacks>
      gtk_widget_show(dialog);
      gtk_widget_destroy(dialog);

      return result;
}

but if you do like this, the dialog will only show maybe 0.000..0001second (maybe
you even can not fell it) then it will be destroyed!! why? because you put
gtk_widget_destroy here. So better way it to put a button (like Close) and put
gtk_widget_destroy in that button call back function (such as clicked);
