Should I make a new wheel?

I must admit that I'm a pythonic,I like everything of python.After a long time to experiment Django. I think I need my own web framework.To tell you the turth,I'm a java fan previously.I like Hibernate,spring,struts etc.So I decided to make a simple but better web framework, its ORM like hibernate, its web architecture like spring, and may be I'll create a simple server, I refer to the Django,CherryPy ,both of them are enough good.may be I just need reuse them. who knows,but for now my plan is write a simple web server firstly. I think cherryPy's server is a good reference.
