As a compromise between the two, I have some code (not committed, and 
currently
very capplet specific) that will take a glade file, and let you hook up a 
GConf key to each widget.  This way, simple capplets can be written with a 
minimal
amount of hassling.  If you want to extend this to be more generic, it could 
be done.

Here's a sample program.

static CappletInfo info[] =
{
	{"checkbutton", "/GNOME/Desktop/CappletTest/checkbutton_bool", 
GCONF_VALUE_BOOL, NULL, NULL, NULL, NULL, FALSE, NULL},
	{"checkbutton1", "/GNOME/Desktop/CappletTest/checkbutton_int", 
GCONF_VALUE_INT,  NULL, NULL, NULL, NULL, FALSE, NULL},
	{"radiobutton1", "/GNOME/Desktop/CappletTest/radiotest_bool", 
GCONF_VALUE_BOOL, NULL, NULL, NULL, NULL, FALSE, NULL},
	{"radiobutton4", "/GNOME/Desktop/CappletTest/radiotest_int", GCONF_VALUE_INT, 
NULL, NULL, NULL, NULL, FALSE, NULL},
	/* ... */
	{NULL}
};


int
main (gint argc, gchar *argv[])
{
	GladeXML *xml;
	GtkWidget *box;
	GConfError *error = NULL;
	GtkWidget *capplet;

	/* init various modules */
	glade_gnome_init ();
	gnome_capplet_init ("newcc", "0.1", argc, argv, NULL, 0, NULL);
	if (!gconf_init(argc, argv, &error)) {
		g_assert(error != NULL);
		g_warning("GConf init failed:\n  %s", error->str);
		return 1;
	}
	g_assert(error == NULL);

	/* Make the capplet */
	xml = glade_xml_new ("newcc.glade", NULL);
        box = glade_xml_get_widget (xml, "vbox1");
	capplet = capplet_widget_new ();

        gtk_container_add (GTK_CONTAINER (capplet), box);
	gtk_widget_show_all (capplet);

	/* initialize the rest of the widgets */
	capplet_info_set (CAPPLET_WIDGET (capplet), xml, info);

	gtk_signal_connect_after (GTK_OBJECT (capplet), "try", my_apply, NULL);
	gtk_signal_connect_after (GTK_OBJECT (capplet), "ok", my_apply, NULL);
	gtk_signal_connect_after (GTK_OBJECT (capplet), "revert", my_revert, NULL);
	gtk_signal_connect_after (GTK_OBJECT (capplet), "cancel", my_revert, NULL);
	capplet_gtk_main ();

	return 0;
}
