Over the years I have acquired fancy furniture that has this form fitting
glass surface. This 1/4" glass presents a tremendously hard and useful
surface. . . .
is there something out there that is "DIY", "do-it-yourself"?

You will probably find all plastics more than 50 per cent as hard
as glass cost more than glass. Depending on the tabletop size,
you may be able to find a (thicker) polished granite replacement among
offcuts from a kitchen counter specialist: but you will have to
pay for its edges to be smoothed appropriately.
