Qt on Rails v0.1 released. But is this Ruby-based Qt and KDE app framework doomed?

Can Ruby do for Qt and KDE application development what it did with Rails for web development? With the Qt on Rails project we're attempting to achieve this - using the clean domain logic and conventions of Rails combined with the brilliant application framework and widget set of Qt. An early 0.1 version has just been released; rough around the edges but enough to show the potential of the idea.
