I once made a simple little GUI generator based on effbot's "Generating Tkinter User Interfaces from XML"[1][2]. I added a tiny parser (written with SPARK[3]) that converted a simple DSL to XML (technically an ElementTree object, the actual XML isn't serialized/emitted at any point) which is then "realized" as a tree of Tkinter widgets with event callbacks.
