Here's a good example using C#. It does a lot more than what you ask for, but I'm sure you can zoom in on the relevant bits...

Choosing the port is up to you. Don't use anything below 1023, because they're pre-assigned to services. You should make your port configurable, because someone else may have chosen the same port, and you'll run into a conflict.

Best practice is to get something above 6000.

Well, you could of course listen on a udp port, and handle the message directly.
The things is when you start doing this, you'll have to handle all the nitty-gritty of opening ports, checking the firewall, checking security, checking if the client can do this operation, etc...
WCF handles all this for you. If you do it yourself, you run the chance of creating vulnerabilities and introduce unhandled conditions in your program.
