Yes; in fact this extension for Flask is similar to how twisted.web works internally.  I think you're looking for something like this:

from klein import run, route

from twisted.web.resource import Resource

class User(Resource, object):
    def __init__(self, user_id):
        super(User, self).__init__()
        self.user_id = user_id
    def render_GET(self, request):
        pass
    def render_POST(self, request):
        pass

@route("/users/<int:user_id>")
def user(request, user_id):
    return User(user_id)

run("localhost", 8080)
