I didn't try any examples, but looking at the easygui site it's pretty clearly a tool for building traditional gui applications in python, and not for doing web applications with tools like web.py.
At a glance without digging deeper I'd guess that to the the problem. I'm surprised you see any results at all.
I've never used it, but just yesterday came across jeasyui.com... a toolkit built on jQuery for making a quick and dirty web application. It looks pretty cool, of course it's based on jQuery which has singlehandedly changed web development in the past few years.
Hope this helps!
