Webwidgets is a framework for writing Web applications as if they were desktop applications. It employs the same programming paradigm as GTK, Qt, etc. with a tree of widgets with callbacks for events such as a button press. It encapsulates page loads, session data, form handling, etc. into widgets with their own state. Webwidgets is focused on code reuse, rapid prototyping, and separation between graphic design, interaction design, and application logic. It is implemented in Python and uses the Webware application server framework.
