How can I make it so people sign up for an email address and it automatically sets it up?
I am using CPanel X, with redhat linux if that is needed.

I am not aware of any tool which can be in co operated with cpanel to do this job.

But i would suggest you to write a script which will do the following.

1) accept the input ie email address and password
2) pass the input obtained to the cpanel script /scripts/addpop

This will get your work done...also if you need you can add a GUI for this
