Locating child-widgets (by name) without Glade-code

[Gus Koppel <gtk spamkiller bytechase cx>]

Is there an (official) way in GTK+ 2.2 to get a pointer to a GtkWidget
by the name of the widget, like Glade imposes it by its lookup_widget
()-function and GLADE_HOOK_OBJECT ()-lists?

Since I intend to create, remove and modify widgets dynamically at
runtime on my own I can't / don't want to make use of Glade's extensions
(if it's avoidable).

And if there isn't a similar GTK+-function (as I suppose), is using
gtk_container_get_children () and recursively comparing the names of the
children against the searched one the correct + most efficient way?
