You CAN do it and do it well. There's a product called Well Bond that you can first apply and then over that use very good quality milk paint, I think the brand is called Schreuder but I'm not sure thats right. You can use a roller for a paint delivery system but always use a brush to evenly spread the paint. It doesn't have to look like a factory finish, just a nice piece of painted furniture. You should probably use a nice warm off-white. Don't forget to get new knobs or pulls. Oh, also, are your hinges exposed? If not you're better off and will end up with a cleaner job. Don't let them scare you off. This isn't so hard.
