There was another thread where someone posted a link to a program that will sync Google Calendar to Outlook. It was actually a thread with a different topic so I can't seem to find it again.
But a Google search for Google calendar Outlook sync gives a bunch of results. Some pretty technical and free. But here's one of many commercial programs. I believe there are free versions as well: Share Outlook Calendar Free, Google Calendar Sync, Pocket Outlook Google Sync - SyncMyCal
