Just set the button used to lauch the window to insensitive in the
"clicked" callback:

void 
button_clicked (GtkWidget *widget, gpointer data)
{
   gtk_widget_set_sensitive (widget, FALSE);
   /* now show the dialog */
}

And make the button sensitive again in the "delete_event" handler of the
dialog.

I think you're right.

You could loop through all the rows with gtk_clist_get_row_data. But that
counts as doing it yourself, I guess. :)

Maybe you should look into the source code to see if there is an easier way
of doing this.
