When it comes to producing a show, it's not about age; it's about money. It's investing in a show that will do well and not get you in debt. It's a risky thing to do. Not just in paying for the venue, actors, techies, and everyone else. Producers also invest money in advertising and so much more.
As for writing a show, there is no age limit. But odds are, the older you are (specifically more experience and knowledge of how plays and such work) the better you are going to be. Anyone with the ability to write in complete sentences can write a play regardless of their age, but that does not mean it will be good. That depends on the how long you are exposed to good writing/theatre, how long you have been writing, etc.
If you want to write a musical, then you would have to at least know how to play piano. It all depends on how much you are doing yourself.
Point is, it's not age. It's experience. The more you have it, the better you will be in whatever you take on.
