import atom
import gdata.calendar
import gdata.calendar.service
import time
 
TIME_FORMAT = '%Y-%m-%dT%H:%M:%S.000Z'
CALENDAR_URL = 'http://www.google.com/calendar/feeds/default/private/full'

        self.username = username
        self.password = password
 
        service = gdata.calendar.service.CalendarService()
        service.email = username
        service.password = password
        service.source = 'GoogleSms'
        service.ProgrammaticLogin()
 
        self.calendar_service = service
 
    def send(self, message):
        event_time = time.strftime(TIME_FORMAT, time.gmtime(time.time()+60))
 
        event = gdata.calendar.CalendarEventEntry()
        event.title = atom.Title(text=message)
        event.content = atom.Content(text=message)

        reminder.method = 'sms'
 
        when = gdata.calendar.When(event_time)
        when.reminder.append(reminder)
 
        event.when.append(when)
 
        try:
            # Add the entry to calendar
            cal_event = self.calendar_service.InsertEvent(event, CALENDAR_URL)
        except gdata.service.RequestError, request_exception:

    sms = GoogleSms('account@gmail.com', 'yourpassword')
    sms.send('Alert!')
