So I'm still not sure about your plans for the doors. What I did for my first few stands was this: For the doors I used 1/2" plywood, some edge banding, and some moldings from HD/Lowes. I cut and glued on the moldings to make it look like a raised panel. Used the heat activated edge banding to hide the plywood end grain, two hinges and it's a door! Even simpler than the hinges (and for a cleaner look?) you could use rare-earth magnets and just "stick" the doors to the frame.. Your doors can be as simple or as complicated to make as you want.
After making the stand, my wife decided that I needed to make some kitchen cabinets to add to what we already have. 8 raised panel doors, 4 with cathedral arches and glass panels, and a new counter top to match and it'll be finished!
However you do them, HAVE FUN!
