"Hildon technology" here means effectively Gtk+[1]...

...which makes these sound a bit funky. If you use *anything*
GUI-related that is already implemented, you'll drag Gtk+ in. Which
will mean that you need to have both Qt and Gtk+ libraries in memory
at the same time, which I think is not too hot on the current
hardware.

If you make an implementation that doesn't use Gtk+ at all, you'll
effectively be re-implementing the GUI part, so talking about
"porting" apps to it is unfeasible given the differences in the
toolkits. Although I have to say that I have never really introduced
myself to the Qt API, I am guessing it's not that compatible even on
the concept level to Gtk+.


[1] The widgets are Gtk+, the UI uses Gtk+ everywhere and even the
input method is implemented on the Gtk+ level (which has reasons, but
is generally considered a bit wrong, X input method would've been
better wrt non-Gtk+ software, but...)
