An easy way to do it would be to use Visual Basic--FIRST sent out Visual Studio .NET to every team, so your team should have a copy.
This is a white paper I posted containing a .dll for a dashboard custom control I wrote for visual basic. I don't know if you've used visual basic before, but a GUI is very easy to create, and to use the control you just create one on the form, set the port property, and then double click it to edit the newpacket event handler to process the inputs.
