Anytime you make doors like that there is a risk of warpage. If you want the solid wood I would just do it. All you can do is put however much finish on the front of the door as the back. As far as making the doors, what I would do is glue up a large panel and match the grain. Then cut the doors and drawer fronts if any and keep tract of how you cut them out and hinge them so it goes on the cabinet like the large panel was. That way the grain from one door will pick up on the next door and look like a solid sheet when the doors are closed.
