So would I just make a box with the hardwood 2 x 4's or should there be a
foot in the middle for added support? How thick should the plywood? Is
it
possible to purchase metal laminates to cover the front and sides of the
platform?

3/4" plywood is plenty. You can make the box from plywood, use the plywood
for the top and then add a matching edge band that irons on to hide the
plywood edge. You can buy plywood in birch, maple, oak at Home Depot. Other
wood suppliers carry an even better selection.

Depending on your decor, you could use brick instead of wood. Or use 2 x
4's and plywood, then put ceramic tile on the edge. Many possibilities
depending on your taste.
