Kiwi is a PyGTK framework for building graphical applications loosely based on MVC Model-View-Controller (MVC) and Allen Holub's Visual proxy. Think of Kiwi as a high-level, object-oriented layer built on PyGTK.

Its design is based on real-world experience using PyGTK to develop large desktop applications, which use many concepts common to most graphical applications: multiple windows and dialogs, forms, data persistence, lists and high-level classes that support domain objects directly.
