[racket] Adding repl like in drracket to application

Hi,

I was wondering if there was an easy way to add a full-featured repl
(like in DrRacket) to an application. Is there widget or something
that I can just use to get full functionality or do I have to
implement keybindings and such myself?

Thanks!
