I've got it running somewhat using:

class httpResource(resource.Resource):

    implements(resource.IResource)

    def __init__(self, service):
        resource.Resource.__init__(self)
        self.service = service
        self.putChild('RPC2', Example(self.service))
        self.putChild('formtest', WebForm(Implementation()))

    def render(self, request):
        self._clientIP = request.getClientIP()
        return resource.Resource.render(self, request)

    def render_GET(self, request):
        """Process HTTP GET Requests."""
        print 'GET: request ->', request
        return '<html><body><h3>Not Implemented</h3></body></html>'

    def getChild(self, path, request):
        """This method handles http calls"""
        print 'getChild path:', path
        print 'getChild request:', request
        if path=="":
            return httpResource(self.service)
        else:
            return httpResource(self.service)

components.registerAdapter(httpResource, IowwService, resource.IResource)

def main():
    """"""
    application = service.Application('OWW', uid=1000, gid=1000)
    s = owwService()
    serviceCollection = service.IServiceCollection(application)
    internet.TCPServer(7080,
appserver.NevowSite(resource.IResource(s))).setServiceParent(serviceCollection)
    serviceCollection.startService()
    reactor.run()

Now I need the form to render, all I got was the h1.
