Old stuff (Score 3, Informative)

This isn't really new. A qtmozilla was implemented by Trolltech a couple of years ago. Then it became an open source project hosted at http://www.mozilla.org/ports/qtmozilla/.

Anyway this wasn't the same than a KDE port, but given that the Kecko Team have not integrated KIO, KWallet and KCookieJar already, they aren't there either.
