Is development of Ubuntu phone on other platforms possible?

view story

http://askubuntu.com – When I first read about Ubuntu phone I became very excited about it. However, I am disappointed to see that if I want to get started I should download and install Ubuntu first. While I can totally understand this (it's pretty much the same with Windows phone and iOS), I prefer Debian on desktop and I don't want to get rid of it, although I couldn't find the qml toolkit for Debian, nor Windows. Is there any chance that developer tools will be released for the above mentioned platforms? (HowTos)
