Glass has to be ground. The grinder is expensive because it is a precision machine. You can buy magnifying glasses very cheaply, so there is no reason for you to try to grind your own.
Mirrors for astronomical telescopes are often made by hand. That is not a hard process but you have to have a room for the purpose, and it takes some time. Even then it is cheaper and easier to buy one already made.
