I am with Edin here, the basic instructions should be as simple as possible.
Running multiple php-versions is an advanced 'task' and IMHO not of interest for someone who wants to start with php.
Something like 'running multiple versions' should be presented as FAQ.
Running php-gtk is covered by the gtk-maual?
Thus said, I would insert pointers/links to that FAQ, gtk-install instructions, pear setup on windows, etc.
To get up and running with php newbies typically select one webserver, one php-version and they will be happy if the setup can be done with few instructions.
No FAQ please. The installation instructions should be in the installation part. You would not like to duplicate the OS/Server structure in the FAQ I guess. But we will need advanced instructions for Win IIS, Linux Apache, etc... So keep the advanced instructions in the install part after the basic instructions...
