Yes, it is. Please use "Necessitas ":http://qt-project.org/wiki/Necessitas to port and use your app on Android.
Also, if you click on the the grey "necessitas":/search/tag/necessitas tag in the upper right corner of this page, then you will be taken to a results page that gives you a lot of content and other discussions which have been had about Necessitas and using Qt on Android.
