Something like this with pop studs on the top for a cover would be great.
Dropping the boom on it, not so much.
You can easily get frameworks like that made - Vetus have them for example custom made to fit your boat with toughened glass panels. However, they are not cheap and it is difficult to make them look attractive as add ons to a boat not designed for them.
The one in the original post looks like a reinforced GRP moulding with polycarbonate panels. Needs a bit of skill to get the framework rigid enough but otherwise not difficult to make - although getting the aesthetics right is a challenge!
