I agree with Flem, I've cut many trees, some very large, split, humped em out, sawed, seasoned, resawed, and ground them for glass bow lams and risers. It can be every bit as much work as cutting wood for selfbows... more even.
I can't say which is easier to put up, selfbow wood or glass bow wood because it depends a lot more on the tree and location than what type of bow it will be used for. Selfbow and backing wood can be 'easy' if it has easy access, a tractor loads it onto my trailer, and my buddy's skid loader unloads it onto his sawmill, he cuts it up, then loads it back onto my trailer. There's been a few times putting up selfbow wood has been super easy, relatively speaking... not that I'm either complaining or ungrateful because I've really busted my butt plenty of times getting wood home and put up.
Sure, buying ground lams and riser wood from a supplier and assembling a glass bow is 'easier', but not if you do every bit of the tree cutting and seasoning yourself, by hand. I know others who do it too. I've checked the man hours in various types of bows when I do all the work myself(except making fiberglass) and there can be practically no time difference between selfbows and glass bows. Actually, it depends more on each bow as an individual.
Heck, plenty of times when I bring a big osage, mulberry, ironwood, cherry, etc tree home, it ends up being used in a wide variety of bow types... selfbows, backed bows, glass/wood lam bows, etc... all from the same log.
A couple weeks ago I brought that giant mulberry log home, that was a rough one. That one hurt.
Just yesterday I looked at a big triple trunk black cherry tree that blew down at my mother's place. There's glass bows in it, and some trilam material... it's going to be a ton of work too, but I don't mind. I like black cherry under clear glass. An underrated wood imo. I'll get going on that thing as soon as it quits raining and dries up a little.
People have no idea what some of us go through or spend to have good, seasoned bow wood to work with... regardless of the kind of bows that result. I wouldn't answer a question like "how much does the material cost?".
