Why not create one yourself? It won't be too difficult - simply create a PHP file that has a form in it that parses the username that has been entered ($username) to a bash script which then runs the commands via the unix terminal. You can use:
shell_exec("yourscript.sh")
and create "yourscript.sh" within unix/linux to contain commands like:
cd /fs/$username
mkdir rt
cd rt
vi index.php
mkdir ss
cd ss
vi index.php
mkdir java
cd java
vi index.php
Obviously it'll take a bit more work, but that's the general idea.
