Regardless of qt, you can actually already write android and iOS apps in python via kivy (http://kivy.org/#home).
It includes a domain specific language for creating widget trees called kivy language, which I hear is not unlike qml (though I haven't tried the latter), though it all maps straight to pure python if you want to write things that way.
