This config seems simple enough that it doesn't seem that necessary to use XML.

Don't you need to provide the controller with a CGI object? I guess this
part hasn't been necessary yet, so the widget controller is just like a
hash allowing widgets to be associated by name.

A widget type has already been defined. So I don't see that the method to
output it's display should be called html() which is, well, HTML specific.
I prefer
print "First Name: ", $widget->display(), "\n";
Since widgets are components that know how to display themselves whether
its WML or HTML or whatever.
