We used Perl/Tk for GUIs on that old system. It brimgs the ease of Tk GUIs to Perl:

Perl/Tk has always been a red headed stepchild since it is a fork attempting to implement a C API that doesn't require Tcl to be linked. Because of that, it has long missed out on significant improvements to Tk over the years. Python Tkinter avoids that by just wrapping around a Tcl interpreter.
