Something like this?

void
Gtk_alerta::destruye_objeto_cb(GtkWidget *widget, gpointer una_ventana)
{
  gpointer el_objeto;

  el_objeto = gtk_object_get_user_data (GTK_OBJECT(una_ventana));
  //g_print("El objeto vale: %x\n",el_objeto);
  delete static_cast<Gtk_alerta *>(el_objeto);
}

Gtk_alerta::Gtk_alerta(const string &titulo, const string &un_texto,
                       const string &un_boton)
{

  la_ventana = gtk_window_new (GTK_WINDOW_DIALOG);
  gtk_window_set_title(GTK_WINDOW(la_ventana),titulo.c_str());
  gtk_object_set_user_data(GTK_OBJECT(la_ventana), this);

  ...
  gtk_signal_connect (GTK_OBJECT(el_boton), "clicked",
                      GTK_SIGNAL_FUNC(destruye_objeto_cb), la_ventana);

  ....

}

Hope to help you.
