In theory, yes... but you'll have to do the vast majority of the heavy lifting
yourself.
iText, as is, has high level APIs to get and set XFA field values. And that's
it.
You'd have to generate the XML yourself and add it to the appropriate place in
the PDF. You could use the PdfFormField class to help you build the fields,
but there's still quite a bit of work to be done.
And if you want a /dynamic/ form, you're in for a whole new set of headaches.
So you need to modify iText to allow you to write XFA, and then use the
relatively low-level PDF objects to do the rest.
Oh, and there's no such thing as a "NeedAppearances" flag in XFA forms, so you
need to draw all your appearances in the appropriate places (values go in the
annotation appearance dictionary, everything else goes into the page contents).
And on and on. Structure, marked content, lions, tigers, and bears. Oh My.
Yes, I have looked into implementing this... why do you ask? ;)
