You might like to take a look at the "Self-Defeating Beliefs Questionnaire" I developed some years ago and which my colleague Richard Lakeman extended into an online version. You can access this at the following link:

I wonder whether incorporating such disparate approaches as CBT & Gestalt might be a bit ambitious?
All the best with your project. I would be interested to hear more as it develops.
