Using HTTP via CGI or Tomcat or otherwise would be one potential 
choice, possibly viewing the UI using the old Mosaic port.

The older curses would be portable and familiar to C developers, though 
that well predates the more common and familiar ncurses.

Or use X11 with CDE or Motif, though that too is quite dated.

Maybe port termbox2 <https://github.com/termbox/termbox2> to OpenVMS as 
an alternative, and the effort involved with porting that code to 
OpenVMS should also increase familiarity with OpenVMS programming.

SMG has been mentioned, and that has been discussed here over the 
decades. Including previous discussions of the SMG calls that cause the 
most confusion.

If you want the full OpenVMS experience, scrounge yourself copies of 
the FMS or DECforms layered products somewhere, and write yourself a 
truly non-portable app.
