Why not pass the dialog as callback data? i.e.

gtk_signal_connect(button, "clicked", callback_func, dialog);

void callback_func(GtkWidget* button, GtkWidget* dialog)
{
	gtk_widget_destroy(dialog);
}

You can gtk_widget_set_sensitive(button, FALSE).

You'd need to figure out some way to do all the signals; you could
possibly connect a second callback to the error dialog which re-sensitizes
the button in the main dialog. 

Don't forget delete_event on your dialogs, that can also make them close.
