JLPT Module on CPAN?

I have yet to post anything to CPAN. I have been putting together a few ideas. The most likely will be a tool for studying for the Japanese Language Proficiency test. To start I would just like my code to generate vocabulary lists and keeps track of memorized words. Another thing to keep track of is memorized kanji.

I could then use it as the engine for a JLPT test preparation web app.
