Glade, a Gnome GUI builder, takes a very similar approach.  There's a
function supplied with each glade project that accepts a widget and a
widget-name.  This function walks the widget->parent chain to the top
of the widget hierarchy, searches all children for a widget with a
matching widget-name, and returns a pointer to that widget.  The
widget-names are set at widget creation time using the
gtk_widget_set_data() function.

You might want to prototype your app using Glade.  This would give you
a working example of this approach, and you may well end up liking the
glade-generated code well enough to use in the production version of
your application.
