The answer to this will probably depend on whether you are targeting Mango or not.

If you are targeting v 7, you will need to look into Notifications. This MSDN article will give you some good information as a starting point.

In Mango (7.1) you can accomplish a lot more manipulation of tiles from inside your app. This MSDN article is a great start point for that.

Please note, however, that your user will need to have the application tile pinned in order to get the behaviour you are describing.
