Google Calendar integration

Might it be possible to include something like this: https://github.com/bubbl/SimpleGoogleAlarmClock ? (or https://github.com/ehamiter/get-on-the-bus)
 It would be great if the alarm could pull alarm times from google calendar, it is very easy to set up alarms that way from any place in the world on any device.
