PHP-GTK Community : a community site for PHP-GTK

Hi all, i have a php-mysql web application, which is a school based project.

My client wants this application to be converted into a .exe file such that it can be installed on his desktop and use it.

Instead, I suggested that we will do the same application using PHP GTK so that it can be run stand-alone on his system.

Will the mysql database be accessible for the GTK application, or do i need to use SQLite database?

Moreover, my existing app has a lot of html forms, with javascript and css included in them. Will the GTK support them ?
