Rainlendar Google Calendar. It is a very lightweight application that doesn't use much system resources or take much space on your. Your best bet (and by far the easiest too) is to use rainlendar.

This is for anyone who likes to use rainlendar to sync with their google calendar, but would also like to sync their tasks to google calendar as well. I have been a google calendar user for many years now but i know it is not compatible with rainmeter any more.
