Facebook calendar application

I'd like to make a facebook page with a customized application. Basically it's an event calendar that anyone can add to (so long as they have liked the page). The calendar can be sorted by anyone by date, country, region, city, event type, etc. There will be a world map as well that places a colored pin on the site for each event. The user can change the date or range of dates to see what events are happening at that time. They can click on the pins to get info of that particular event. As administrator, I will be able to edit or erase events when necessary. Once the event completes, it will auto erase from the map/calendar/etc. Let's get the bidding started!
