I doubt there will ever be a Net Stumbler or Mini Stumbler port as these are closed source Windows applications. Wellenreiter was ported to the Sharp Zaurus platform which is also ARM based. Hopefully someone may be able to port this application to the 770. It does everthing on your wish list and is GUI based. I would be happy with a working copy of Kismet (without the hundreds of "ghost" networks).
