[Twisted-web] Can someone translate this, please?

I am trying to get my head round Twisted, particularly to use it as a 
simple web server (using http as a RPC mechanism, really). I was thinknig
of using a "Rosetta Stone" approach, and am wondering if someone could 
translate this ordinary Python program into Twisted, please:

=====================================================================
# simple_http.py = a simple http server

import SimpleHTTPServer
import BaseHTTPServer
import StringIO

template = """<html>
<head>
<title>%(title)s</title>
</head><body>
<h1>%(title)s</h1>
<p>Path is [<tt>%(path)s</tt>]
</body></html>
"""

portNum = 1450

class MyRequestHandler(SimpleHTTPServer.SimpleHTTPRequestHandler):

   def do_GET(self):
      args = {
         'title': 'simple_http.py',
         'path': self.path
      }   
      result = template % args
      self.send_response(200)
      self.send_header("Content-type", "text/html")
      self.send_header("Content-Length", str(len(result)))
      self.end_headers()
      f = StringIO.StringIO()
      f.write(result)
      f.seek(0)
      self.copyfile(f, self.wfile)
      f.close()

print "===== starting simple_http.py on port %d =====" % portNum
server_address = ('', portNum)
httpd = BaseHTTPServer.HTTPServer(server_address, 
   MyRequestHandler)
httpd.serve_forever()

#end
=====================================================================

As you can see, it's very simple. When it recieves a GET request it just
sends back an HTML page saying what the path in the GET request was.
