Hi Ralph. You should be able to accomplish this with Event Tracking in GA. See: http://code.google.com/apis/analytics/docs/tracking/eventTrackerGuide.html
From that page:
"In Event Tracking, each interaction with a tracked web page object is counted, and each interaction is associated with a given user session. In the reports, Total Events are calculated as the total number of interactions with a tracked web page object. On the other hand, where a single user session (or visit) has one or more events, this is calculated as a single Visit w/Event, or Unique Event in the reports.
For example, if one user clicks the same button on a video 5 times, the total number of events associated with the video is 5, and the number of unique events is 1."
Hope that helps.
