Per http://groups.drupal.org/node/9447#comment-37063:

There are at least three major ways of integrating Google Calendar into a Drupal site.

1. Create a static page on your drupal site and embed the Google calendar in it, so it looks like the calendar is more or less natively hosted on your site.

2. Use the Calendar iCal module to subscribe to your Google calendar and have those events show up in your Drupal Calendar view

3. While I haven't really explored this, I understand there are plans for something similar to Feed API for iCalendars, which would actually create event nodes on your drupal site based on events in an iCal feed (e.g., from you Google calendar). In this way, you would use Google to create and manage the events, but be able to display the events as nodes on your drupal site.
