Creating a gravity form in php

I'm making a looong job application form with Gravity Forms. There are chunks of fields that would be so much easier to handle in php (even I can't use loops, copying and pasting would save heaps of time). I've looked through the documentation but I can only find hooks/filters for forms that have already been created. It is possible to register a form or create one in php that hooks into Wordpress?
Hope I didn't miss something obvious. Thanks in advance.
