wall planner

I have a "wall planner" application, that shows who is out of work and when they're due to come back.  Its done in asp.net with the 1.1 framework, but is only a text mode application.  I'm going to migrate it to the 2.0 framework in VS 2005 and turn it into a graphical app.  The interesting thing is that nobody seems to have done a wall planner component, so I'm going to have to write it from scratch :-)
