You can make an application on Google's Summer of Code website.

It looks to me that your proposal may well not be implementable in the
time available for the Summer of Code, so you might want to pay
attention to this when making a detailed proposal.  In particular the
GNU project's summer-of-code mentors will be seeking to select useful
and achievable project proposed by people who have a high chance of
success within the limits of the available time.  You may wish to
think about how you can refine your idea to reflect this.
