GUI editor looks nice and useful!!

How much work would it be to make it compatible with my "DataFile" format? url: http://www.necrosoft.nl/?p=790 It has nested elements, more like simplified readable XML. It only needs to place image, text, edit, panels and button elements with some small configurations like text and image.

just a question... I'm looking for a simple UI editor. And I don't want to make one myself .

Nice work!
