wxGlade

wxGlade is a GUI designer written in Python with the popular GUI toolkit

wxPython, that helps you create wxWindows/wxPython user interfaces. At the

moment it can generate Python, C++ and XRC (wxWindows' XML resources) code.

As you can guess by the name, its model is Glade, the famous GTK+/GNOME

GUI builder, with which wxGlade shares the philosophy and the look & feel

(but not a line of code).

It is not (and will never be) a full featured IDE, but simply a "designer":

the generated code does nothing apart from displaying the created widgets.

If you are looking for a complete IDE, maybe Boa Constructor or PythonCard

is the right tool.
