I suspect most people are going to want to use this with their existing Google calendar, so it'd be nice if you could just click a button, authenticate with Google, and then pick calendars from your Google account to use. This would be way easier than adding calendars one-by-one, certainly.
FullCalendar has support for loading events from public Google Calendars: http://fullcalendar.io/docs/google_calendar/ . I don't know if it will support loading private Google Calendars if you authenticate with Google first?
