Tkinter and django

[Ismatus3]

Hello everybody
I'm trying to use Python and Django to make my first website , i followed this tutorial : http://webpy.org/docs/0.3/tutorial , and i could finaly while the execution of the Python code nouveau_fichier.py which is :

#! /usr/bin/python
# -*- coding: utf-8 -*-
import web        
urls = (
    '/(.*)', 'hello'
)
app = web.application(urls, globals())
class hello:        
    def GET(self, name):
        if not name: 
            name = 'World'
        return 'Hello, ' + name + '!'
if __name__ == "__main__":
    app.run()

and in opening the link given from de Terminal : http://0.0.0.0:8080/ , i could find a web page that contain : Hello, World! .

Till now i have two separated questions :

1) when i run the python code : nouveau_fichier.py ,to be able to access to the web-page that print "hello, world!" , i need to leave nouveau_fichier.py executed , so i just need to know how : to start and turn off the server from a command ..

2) the second essue is that i need to know if i can use Tkinter in my code Python that prints labels , entries ...

Thank you very much for your answers .
