Not finding much time to work on the as3googlecalendarlib (http://sujitreddyg.wordpress.com/2009/01/29/as3-library-for-google-calendar-as3googlecalendarlib/) or the sample application using the library. I managed to create a simple API documentation for classes which should be used to consume Google Calendar service. I also created a document in which there are code samples on how to create a calendar and calendar events.
I will add more to these documents and publish a proper API documentation and yeah a sample application ASAP. 
I have the sample application running with minimal features, but wanted to add more.
Snapshot of the sample application developed using this API.
