At the very least, you would need some therapist knowledge about the person using such a CBT software. Likely from your actual therapist, but it could be done with a lot of self-introspection/discovery - the problem with the latter is that if you come to the wrong conclusions about your own problems and solutions (which is likely) it could lead you further astray. So every copy of it would need to be very customizable and very private at the very least; medically certified, maybe.
