Google Apps Script could be used to create and edit forms and to send and read responses. The specific service is the Forms Service but if send responses to a Google Sheet you could read the responses from there.

Note: Be aware that the responses sent to a Google Sheet are not synced back with the Google Form, in other words, if you change a value o a Google Sheet the original value is kept unchanged on the Google Form.
