Well, you'll still have quite some work to do. 

I'd like to add that moving from QListView to a model/view is not that
hard at all, once you understood the model/view way. Actually I ported
an application (that I did not write myself, i.e. I had little idea of
the code) to Qt4 and replaced all QListViews (which where used heavily)
with model/views. I could reuse quite some parts of the code in the
model, i.e. all code that extracts information from the underlying
data structures.

Also you might not even need to write your own view, the Qt classes can
already do a lot.
