[plt-scheme] DrScheme Interactions window

Actually, I'm developing a program that conjugates verbs in Spanish and
French. I'd need of course to have some way of putting the information
needed for conjugation (the subject of the sentence and the infinitive of
the verb). I'd also prefer this to run in its own application with a name of
my choice (even if it only looks that way and in reality it is running in
DrScheme). Also remember that I am only working in version 204.
