This application is an example of php GUI app using Glade(GTK). Application realises interface for calculator. It has two files: calc.php - php instructions(the file that should be run) calc.glade - glade interface Glade file may be changed in any Glade editor(I used Glade Interface Designer). To make it works you need PHP 5.1+ with php-gtk installed. Latter may be found here: http://gtk.php.net/download.php
