In fact I'm speaking about this http://www.qualitysystems.com/qs/toolbox/index.html, the tool they promote, not directly the frontend of the site (I agree with the code source)
You can see that the tool they sell looks really really really like the CMS Plone2.xxx. I'm pretty sure that if someone has used Plone2.x he will recognize it and every kind of skin , button,user interface,edit action, sort ,.... is copied from Plone. That's why I believe the tool has been made with Plone. I would be interesting to have Plone user opinion.
