John,
You can find several good Windows Service tutorials at CodeProject.com. Here is one example (I think I used this a long time ago) http://www.codeproject.com/dotnet/simplewindowsservice.asp

In addition to getting more familiar with Windows Services and .NET I would suggest to try to create a simple console app or a simple windows form app and use the same principle as you described in your original post. It will be easier to debug.

Just my $0.02 worth.
