Thanks.

It's much the same of course, but yes that would be nice.

There is. It comes with the dev flavour of the Gtk+ installer.

We do have slightly different terminology in a few places and usually
for good reason. For example the idea of a callback function makes a lot
of sense in C where you really do have to have a named function that
gets called in response to a signal. I Haskell we don't need a named
function of course we can just say:

onClicked button $ do
  ...
  ...

I'll send you some more comments when I've had a full read through.

Perhaps we should use the haskell.org wiki for this.
