Yep, I prefer it too.

I've attached an example which (I think) addresses all these questions.

Instead of returning a list of tuple(label, annotated types) return an
instance of formless.MethodBinding, whose constructor accepts an
action="My button label" kw argument

In the example I have done this by providing my own form template
'Pattern', but another way might be to register your own
MethodBindingRenderer adaptor based on the one in formless/webform.py.

There has been talk on #twisted.web of removing the slot system and
encouraging use of render_ methods instead, so this example may need
altering in future. Perhaps Donovan or one of the other developers might
comment on whether there is a better / more future proof way of creating
custom forms. I might just have not understood what was being talked
about though. :-)

You might also want to look at pollenation's 'forms' system which works
at a lower level than formless / freeform...

Hope that helps.
