Windex : Open Source, unsupported, works with GNAT and maybe
ObjectAda, reasonable subset of Win32.

GtkAda : Open Source, supported by ACT, full GUI interface, portable
to other windowing/operating system

Windex "competes" directly with Claw and GWindows. I wrote it because
Claw was not open source, and GWindows was not available. I'm not
clear why David Botton wrote GWindows instead of extending Windex.
They do have different designs under the hood.

GtkAda also competes, but since it's strictly a GUI binding, not an OS
binding, and it is platform independent, it's in a different class.

Jewl could probably be written on top of any of these.
