I think Rudy means how to start learning to develop a jailbreak Marie
If you have no development background then you have a big hill to climb. Developing a true jailbreak is an order of magnitude more complex than writing a complex application
A great book to get you started to see if it is even for you is "Hacking: The Art of Exploitation" by Jon Erickson.
Most people in the field agree that a strong grounding in Assembly Language is key. To begin with you might like to learn on a platform like IA-32 (intel), but you will then need to migrate to ARM later in the future...
Again, you might like to start with "Assembly Language Step by Step" by Jeff Duntemann
Hope that helps.
