python The TraitsGUI project from the Enthought Tool Suite contains a toolkit-independent GUI abstraction layer (known as Pyface), which is used to support the "visualization" features of the Traits package. Thus, you can write code in terms of the Traits API (views, items, editors, etc...), and let TraitsGUI and your selected toolkit and back-end take care of the details of displaying them. You can use Qt or Wx backends.
