Try doing it in the __init__ of the class, with logic something like this
(typed from memory, so there are likely to be errors):

   def __init__ (self, request):
       Form.form.__init__(self, request)
       self.add_widget("submit_button", "add", ...)
       if self.get_widget_value("add"):  # XXX not sure this is the right
check
           self.add_widget("string", "fieldname", ...)

Note that Quixote comes with a List widget for having a list of identical
subwidgets;
the user can add new ones so they can enter an arbitrary number of items,
and
I think blank fields get forgotten, so you may not need to do this dynamic
widget creation yourself.
