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

hi all

I need help here, I'm building a linux based screen reader applications using php-gtk. after googling, I get some information

1. gnome already has an AT that can be accessed is called the AT-SPI.
2. AT-SPI built using corba language (. Idl). for a variety of languages already support this, especially I can find for java and python. I can not find documentation for php-gtk.

"My program" will access the desktop and its application through the "AT-SPI". I do not know if this is right or not, because when I read a few articles on the site gnome.org all the articles point to "AT-SPI." so, the point I want to ask is "how do I access corba using php-gtk?"

merci
