I would recommend capturing the user input using XForms, and then using XSLT
to take the XForms instance as input and generate (or parameterize) the
XQuery as output. Then you can string the whole lot together using something
like Orbeon, which provides both an XForms processor and an XProc-like
pipeline processing language.

You can also, of course, do another XSLT transformation to process the
XQuery results into the XHTML (perhaps with embedded XForms for the next
interaction) that you want to display back to the user.
