Find more mentors to help with organizing and running your programming students.

And before I get any "One does not simply find more mentors" memes... Ask the students in your group if any of their parents have a background in programming or IT or even organization/management. Get them involved. Ask your existing mentors to help with finding more mentors. Ask for help. Be open with your communication. Ask other students in the group to step up and lead development efforts.

Monochron hit the nail with his post. You need leaders to help spread out the opportunities you can make available to your new programmers. As Jared mentioned, there are a lot of cool things they can be doing.
