hello, this is NOT a plugin, this is kinda of a web application, which runs on a PHP+APACHE webserver. It can run a PC on the same network of the ZS machine or on a remote webserver with curl and https client connections enabled.
To make it work under windows you can install EasyPHP and then put the files in the /www directory, then edit the configuration.php file with user, password and the IP of the ZS interface on which the web interface is running and then type into your browser http://127.0.0.1 EASY!
