"I want to write Python code that spits out the HTML and JavaScript required for these interfaces and I still want to handle all the logic in Python."

This sounds a lot like PyJS: http://pyjs.org/

I used pyjs (pyjamas) for some personal projects and I liked it a lot. Unfortunately it got stuck in time, and in 2012 the current maintainers did a bad political move, and left the project in even worse shape than it was.

Nowadays, I wouldn't consider pyjs to build anything relevant..
