First off, why are you using an array? Not that it's bad or anything,
but how does it help you where a simple list would not?
Second, what would be nice is if liststore.insert would take an
interable. Baring that you could simplify a little like this:
keys = ['v1', 'v1', ..., 'vn']
for d in data:
selt.liststore.insert(0, tuple(d[k] for k in keys))
whether it is worth it or not depends on how many keys you have.
