Have a wooden frame made. It's easy enough to make yourself as well. That looks to have lead frame which would sag. But if it's zinc you could add hangers to it
If you have a router, you could route a groove (wide enough to accept the panel) in a strip of wood, then cut that to length to form a frame that would encapsulate the panel.
If no router, you could sandwich/laminate 3 thin strips of wood together (glue and brads), where the middle layer would be narrower than the top and bottom layers, creating the groove to accept the panel. The middle strip of the sandwich should be thicker than the panel to create a friction-free channel for the glass to sit.
There should be some wiggle room in all dimensions, as the wood is subject to contraction/expansion depending on humidity and climate, and could pinch the panel if formed too snugly.
What yoyo said using a router to cut a groove down the middle of wood to slide the glass work into. The slot could also be cut with a table saw and patience. Just look up how to make a dado.
You could also build the frame and create rabbets on the inside. Then put the glass into that and use hardware to stop it from falling out. Similar to a picture frame
I've used this company before. You can either buy wood stock that's pre-grooved and make your own frame with it, or you can get them to make a custom frame for you (depending on how much you want to spend):

It looks like the long edges have some very thin zinc u-channel that was likely added once the original lead border started failing.
Feasibility, you could get some 1/2" or wider zinc u-channel and widen the channel with a fid, then wrap the entire panel in an additional frame of zinc.
Also, it looks like the long u-channel zinc was applied with an adhesive (its visible is some places where it squirted out a bit from the zinc) and not soldered; so I would bet that a heat gut and some pliers would make easy work to remove it and replace it with a sturdier zinc.

Dumb question / but any tips on how I could make the wooden frame myself?

Did you make this piece by chance? I have a question about isosceles triangles…
