While in theory any tree can be grown as a bonsai, in practice some of them are very, very difficult, particularly if you have them very far from their climate zone.
I tried larches twice, and several people around here have tried them. They want a decent below freezing dormant period, and every single one here has died after the first winter.
Redbud trees grow in the woods around here. I have killed three or four putting them in pots. I have no idea why.
Starting from seeds could give you a nice tree, but you should put them in the ground, let them grow there ten or more years, and be very patient. Unless, of course, your five year old grandson says, "Look, Granddad, there are seeds in my apple. We can plant them in a pot and grow it with your trees." Fortunately two of them sprouted and one is still alive.
