Although it's long, it isn't very wide so the overall glass area isn't that much more than a 48x36" sheet. 4mm glass will add a lot to the weight. 2mm is OK IMHO, that's if you can get a piece that size easily. Wessex (Glass&Mirror) will supply glass cut to size and deliver. (If I were doing this I would order two bits. If the first gets broken, you can use the second for stock.)
Or you could use acrylic sheet. More expensive. Lighter though.
The frame can be strengthened by using the French Cleat method of hanging. If you are unfamiliar I can expand on that later.......
btw. It's advisable to have two sets of hands to handle a piece of glass that size. Unless you have arms like a gibbon.

These are good for fixing a frame
clicky. If you place fixings on the sides and bottom it will support the weight of a heavy frame. I have fixed 3m x 1m mirrors using these. They are also more flush than a french cleat.

Poly moulding is going to be a bit bendy. I would use a subframe to give it some guts.
Check the Big Jobby thread in Members Only.
You wouldn't need to go quite to that extreme. But the principle is the same.

Here's one a similar size with it's happy owner. I used 3mm acrylic to keep it light and braced the frame in a couple of places across the back to keep it rigid. The moulding is Lion L1794 deepish rebate with a paper covered slip.
