D-Bus is useless here, but GtkSettings provides several signals that can
be used as follows:

  GtkSettings *gs = /* get a GtkSettings object */.
  g_signal_connect (G_OBJECT (gs), "notify::gtk-theme-name",
                    G_CALLBACK (style_change_cb), userdata);
  g_signal_connect (G_OBJECT (gs), "notify::gtk-application-prefer-dark-theme",
                    G_CALLBACK (style_change_cb), userdata);
