Kevin, ignore all he naysayers and go for it. If you do your homework, are detail oriented, and aren't in a hurry you can make a beautiful set of cabinets as a first project. Your experience in the trades gives you a good head start on some basic concepts. I'd recommend you build a simple wall cabinet and base cabinet first, one each, start to completion including the finish. You'll learn a lot and will be able to work out a lot of the bugs.
Good luck!

I started with absolutely nothing. Now, thanks to years of hard work, careful planning, and perseverance, I find I still have most of it left.
