Javascript would not be needed, but it could be used to make a smooth "Ajax" communication with the server.  To that end, this article shows how to send data to the server and get the response back into the DOM.

What would be needed are a way to identify the returning client and a data base table to keep track of the clicks.  The client will be identified by the HTTP cookie.  The cookie will be associated with a row in the data base table.  Each time the request is fired, the PHP script will take the cookie, look up the row, add one to the counter.  If a request arrives without a cookie, it's a new client.  The script will generate a new, unique cookie, insert the row into the data base with a count of "1" and welcome the client.

If you're new to application development, this article has some excellent "getting started" learning resources.
