One of the things that I see people have trouble with over and over on their installs (if they even try this), is installing the PHP-GTK software so that they can create GUI apps on their systems. Most developers that want to move into this area have been frustrated at one time or another, trying to get their install to work correctly. Well, the latest article from Zend aims to help you out with that frustration.

For those out there that are lost and aren't sure what PHP-GTK would be used for: PHP-GTK is an extension that allows you to create GUI standalone, cross-platform applications. This extension is not used for the web in any way, but for client-side applications.
Basically, a way to make GUI apps that can be used from the desktop level instead of on the web, as most PHP apps/scripts are used.

An Introduction to PHP-GTK steps you through installing the PHP-GTK software (on Windows) and shows you some basic scripts that give you the fundamentals of the PHP-GTK functions - as well as an example script. It's a pretty cool system, especially if you don't want to have to learn another language just to make GUI apps.
