The OpenStack Dashboard is written in Python and its a web front end which gives Swift as well. I am sure if you will dig the code you will get a good idea about it and then you can write for your own using python https://github.com/openstack/horizon
Hope it helps, also do let me know if your planning to release the dashboard under open source, i won`t mind testing it for you. :)
Good luck!!
