I have a pair of classes I use in my app which implement a window /
dialog tree.

You can have many independent top-level windows, you can freely mix
modal and non-modal dialogs, dialogs can pop up nested child dialogs,
and a modal dialog only blocks windows below it in the tree, leaving
other parts of your app working. It all works with a single
gtk_main().

It is a bit hairy :-( it's all based on continuations and is probably
overkill. But if anyone is curious:
