You can skip Xephyr/Scratchbox/x86 phase completely.
 Skipping Qt Creator phase is an option too.

 Qt Simulator simulates Qt on desktop. Unfortunately.

  You can install Qt libraries manuallly on your N900.

Using Nokia Qt SDK you can compile for ARM platform, install and run application
on connected N900 from the Qt Creator.
Steps are described here:
