It certainly can be done, even in a home shop. You need hardenable spring stock in it's malable form. Then you have to harden it then temper it so it soes not break. If your willing to do it over and over till you learn to get it tempered right you can make good springs.
In a home shop it borders on being a lost art, due to it being so easy to go to a hardware store and buy generic springs for nearly any application.
But if your a paitent person and like to learn by all means go for it. You will be doing something that amazes your friend.
There are many sources for spring stock to work with.
The one I have dealt with is Brownells Gunsmithing supplies in Montezuma, Ia. The Nations largest supplier of Gunsmithing tools and supplies. Their catalog is an amazing book to read.
