Yes, it can. I posted all the instructions for a integration of a
Joomla 1.0.15 and Glossword 1.8.6 on my blog (see below), but
unfortunately it's on Spanish, and I have not found the time to
translate it. You can try using google translate and see if it makes
sense. I promise I'll try to post the full english integration
instructions soon.

Perhaps you can use Google Translate for now, and see if you can make
sense of it.
Good Luck!
