(Author of Gooey [1], a GUI framework for WebASM in Go)
I have also found a UI framework in C++ with OpenGL named Gooey (2008-ish).
And in early 2000, I was in a mailing list for designing a successor/replacement to X11, code-named "Gooey" that never went anywhere.
ooof I did have the nagging feeling I had seen a gui thing with that name before.
I also have one [1]. It's a good name :-)
