I don't think there's ever a good reason to disable the "Back" button in a web application. If you think it necessary, it's time to rethink your process.
That said, there are ways to handle it on the back end so that the user can't submit twice. Have you considered setting a session value at a point that allows creating the account, and then clearing the value once the account has been created? Otherwise someone could just clear their session data and go back to add more accounts. -Brian D.
