What GUI framework did they use for this?
"It's written in C and has custom OpenGL renderer."

I mean, I don't even know what you use to write "windows" applications anymore.
But are the stock frameworks that slow to justify rewriting the toolkit? I am under the impression that writing GUI toolkits was Hard.
Are there plans to make this cross platform?
Agree about the MS offerings. That's why I use cross-platform frameworks (wx, qt) even for the Win-only apps.
