[racket] text-field% isn't just for string input, but for output and numbers too!

May I propose an experiment? While I think that this is a 
perfectly legitimate request, I am also wondering whether 
Matthew's port of the GUI library to Racket has improved 
our user's ability to look at the code and to propose a 
fix. You might consider posting it here for discussion first
before you submit the code as a request [*].
