PHP GTK on how to use

I have no knowledge on desktop applications, but I have a project in our school desktop application and only I know is to make websites using php, 开发者_开发百科javascript, css and etc. I heard about PHP GTK and I already read many articles and tutorial for windows. But still, I didn't understand on how can I start developing a PHPGTK desktop application. I need somebody that will explain to me on how I can install, compile php to .exe to execute it. Or any Idea on how can I make a desktop application that using PHP, MySQL, HTML, javascript or any web language except dontnet. I need a browser free for this. I see a application that uses web language and see what he did but I didn't understand. Here is the name of application "CabalRider".
