Web interface to create a docbook

hi all ;)

that's my first mail to this mailling list so hello to everyone !

Here my problem, I would like to get a web interface (java applet/php/perl) to 
create or modify some docbook document. 
I'm searching a such application for the www.knoppixfr.org website [about 
1500~2000 visits/day]. Knoppixfr's users want to create documentations but 
they do not have in generally good knowledges in xml. 

If you know some projects even not finished. 

thanks for your help
Fab.
