Yes, there's a version of gd for PHP.
http://uk2.php.net/gd

In fact, if you look at the two examples on that page, they give you 
almost all you need to know about merging tile images. The first example 
shows you how to paint one image on top of another. The second example 
paints a generated image onto an image tile with a specified opacity. 
All you have to do is grab the six images and paint them onto a blank 
background with the opacities specified in the request.

Do make sure that gd for PHP is installed on your webhost before you 
start.
