Really weird that he recommends Motif. Motif is not comparable to Web/Gtk/Qt since it has only the most primitive widgets, and no 3D support.

I would propose doing a web-app if you really care so much about compatibility. Web also allows for more custom widgets.

So now you have to support all browsers : Firefox, Safari, Chrome and Edge. Plus some old stuff because this customer still has a Centos 4 Workstation running and another has a few Windows XP PCs that are mission critical.

I don't know if Motif is better at that, but I wouldn't bet on web-apps personally.

Is Motif actually available on modern Linux systems? And is there a Windows port as well?

I find it difficult to believe that Motif is actually that portable.

Web apps are only as portable as the browser features they use, and the browsers available for the platform. A primarily backend-rendered app, with minimal Javascript is much more portable than the average SPA app.

https://www.archlinux.org/packages/community/x86_64/openmoti... lists as being updated 2020-01-05, and https://sourceforge.net/p/cdesktopenv/wiki/SupportedPlatform... claims that CDE supports a rather lot of platforms (which implies motif), although I'll grant that most of those probably haven't been tested in a while.

Still better watch your step. Features can be removed from the platform. https://stackoverflow.com/a/46689336/

What widgets do you feel are missing from Motif ? And why would it need 3D support ?
