David is right.

Before the line
  raise "NULL" if my_form.get_fields().nil?

insert
  raise Ncurses::Form::FORM.singleton_methods(false).join(" ") #=> new

You'll see that FORM class has a singleton "new" method which always
returns a FORM object. Class#new is shadowed so you'll never get a
descendant object

  raise MyForm.new.class.inspect #=> Ncurses::Form::FORM

DelegateClass is a possible solution unless you want to muck with the
C sources.
