You cannot do this with EnumField. All of the standard field types included
with Guacamole that allow you to specify possible values will expect
translation strings for each of those possible values. You would have to
define your own custom field type if you cannot provide translation strings
for the possible values ahead of time.
Is there some other UI element more appropriate?

Yes, convenience functions are provided only for username and password. You
need to use the generic getParameter() for anything more specialized.
