Personally, I always try to avoid using gtk_dialog_run() because you
block on it.

As I understand it, gtk_dialog_run() blocks until a response is received
(one of the buttons is clicked or the window is closed).  

Clicking Help is a response, and without returning you would not know it
had been clicked (especially when blocking).

You could set up a callback and run the dialog without blocking:
        
        g_signal_connect_swapped (dialog, "response",
                                  G_CALLBACK (response_cb), 
                                  NULL);
        
        gtk_widget_show_all (dialog);

then set up a handler for the response:

        void response_cb (GtkDialog *dialog,
                          gint response,
                          gpointer user_data)
        {
                if (response == GTK_RESPONSE_HELP) {
                        /* do some code */
                }
        
        }
        
hope this helps, for more information see the online documentation about
gtk_dialog_run() and other dialog API:
