Stephe Leake has already mentioned GtkAda (for which the GLIDE GUI builder
is available), so I'll just add that JGNAT compiling Ada to Java Byte Code
is another cross-platform possibility.  Regardless of one's opinion of
Java, it does have an extensive set of GUI components, to which JGNAT's
jvm2ada binding generator provides access.

I only know of one GUI builder that generates Ada for a JGNAT/Java
environment, and that's RAPID
(ftp://ftp.usafa.af.mil/pub/dfcs/carlisle/usafa/rapid/index.html).
However, it supports only a limited number of features and capabilities, so
while it's good in an educational/"playing around" setting, you wouldn't
use it for production work.  You're left to roll your own GUI, which I
haven't found too onerous yet :-)
