Python objects to web HTML UI

I'm quite new in web development. I'm building up my Web-Dev knowledge using Google App Engine. For now I'm responding to HTTP requests using webapp2 and rendering my simple HTML pages using jinja2 with support of bootstrap and jquery.

I'm wondering if python has a similar framework to this java based one: http://jello-framework.com/demo/playground.html

Putting UI decorators to classes and properties to have UI binding made easy for developers like me where HTML, AJAX and CSS are quite a nightmare.
