Let me explain a bit more:

With such a function:

void
gtk_builder_build_object (GObject *object, const gchar *file, 
			  const gchar *name)
{
	GtkBuilder *builder;
	GObject *child;

	g_return_if_fail (GTK_IS_CONTAINER (object) &&
			  <typeof object inherits typeof widget(name)>);

	buider = gtk_builder_new ();
	gtk_builder_add_from_file (builder, file);

	child = gtk_builder_get_object (builder, <widget(name).child>);
	g_return_if_fail (child != NULL);

	gtk_container_add (GTK_CONTAINER (object), child);
	gtk_builder_update_object_properties (builder, object, name);
}

it would probably be as simple as overwriting the constructor of the
custom container type, this way:

static void
my_dialog_constructor (GObject *object, ...)
{
	G_OBJECT_CLASS (parent_class)->construct (object, ...);
	gtk_builder_build_object (object, "my-dialog");
	/* connect signals here */
}

the default destroy handler would take care of throwing away the built
objects.

This kind of API would look nice and simple, wouldn't it ?
