Communication between pc and arduino UNO

Hi everyone! I'm starting with the arduino project and i was building a simple temperature sensor that collects data when asked remotely by my pc

This is my setup:

Arduino UNO

Wi-Fi Shield HDG204

PC and wireless connection

I know that the steps I must follow are something like this:

The pc sends the request to my arduino and he responds with the data, the data is then written on my pc

All I need now is an example on how to do it or some information on how to set up properly the server on my pc and the istruction that arduino has to follow.

Any help is highly apprectiated, thanks a lot!

Get your project working first just using the arduino serial monitor, then integrate the wireless part.
