You could probably adapt the org.apache.log4j.chainsaw.MessageCenter and MessageCenterAppender classes available from HEAD to suit your needs. The MessageCenterAppender is designed to be attached like a normal appender to any logger, and stores the events in a ListModel. MessageCenter then just adds that appender to a Chainsaw specific logger for internal events, allowing the user to see what's happening inside Chainsaw. If you 'borrowed' those classes, you'd probably not have to change much at all to suit your requirements (although I can't verify what would happen with 10000 events in it). Hope that helps.
