Are you reasonably OK about hacking a little bit of code together? If so, use the XBS ModGen (find on this site's downloads) to create a module and then edit the user side page(s) to add in the javascript generation.
1/ create a module with a user menu.
2/ do not add anything else to the module (eg menu items, tables, blocks etc)
3/ generate the module
4/ edit the new module's index.php and templates/mytemplate.tpl files to accomodate the javascript that you want to use. Follow the jscript's producers instructions for including the code into index.php in the place indicated by comments in that script.
5/ install the module as per normal
That should take you about an hour (the bare bones module shell just took me 90 seconds.)
Now of course if you then want to use XOOPS to set up the questions and control language strings etc, that is going to take a bit longer but in the meantime you 'll have a working module.
