Chrome Extension with Gmail OAuth Login and Form Submissions

I'd like to build a chrome extension that uses a Gmail OAuth login and that enables users to input non-identifiable information about themselves. In particular, I would like to create a series of forms and reminders that the user would fill in. After adding user data, the user would receive notifications about reminders that he or she has set (they could set a date to receive these reminders). I would like to be able to support lots of user data and store all this information for later reference by the user himself. Please contact me if you are interested in this project.
