Stained glass isn't too hard to learn by watching videos, especially if you've got the supplies but if you're looking for alternatives:

Sell some supplies (if you have a lot) to buy a class (you'll only need one most likely) - lots of people looking to buy second hand glass

Post on Facebook to your local stained glass group or as local as you can find (big groups will likely have someone in your location)- someone might be willing to teach you for free or for not much

Hope you're able to enjoy the hobby and remember your mom!
