yes, of course:

  GParamSpec **pspecs;
  GObjectClass *object_class;
  gint n_pspecs;

  object_class = G_OBJECT_GET_CLASS (object_instance);

  pspecs = g_object_class_list_properties (object_class, &n_pspecs);
  for (i = 0; i < n_pspecs; i++)
    {
      GParamSpec *pspec = pspecs[i];

      g_print ("Objects of type %s have the %s property\n",
               G_OBJECT_TYPE_NAME (some_instance),
               pspec->name);
    }
  g_free (pspecs);

ciao,
 Emmanuele.
