GUBI/GUI builder problems

[DENES Pal <denespal valerie inf elte hu>]

Hi!

I have downloaded the latest (actually quite old) version of GUBI but
didn't find the matching gtk version (gtk+970828.tar.gz) on the gtk site.
Could someone tell me where to find it?  Another question.  What's the
current status of GUBI? What about GLE? What's the main difference between
GUBI and Glade? (Functionality / approach...) Is there / will there be a
usable GUI builder for gtk?

Thanks
