A "Wamp-Server" is just a Apache Server with php & MySQL. So just take a look at my php & MySQL examples ("XAMPP").
For that use httputils which (simplified) sends a string with parameters to a php script. Inside the script the parameters are fetched and you can work with these.
As you give a ip-address or a domain (
www.mydomain.com) you can connect from everywhere (WiFi, GSM).
