Painted wine cabinet

My grandson has requested that I build for him a wine cabinet, similar in style to the typical IKEA furniture (IOW, pretty plain). My initial idea is to build the cabinet with birch plywood, with edges trimmed with poplar. Finish is to be a satin black.

I've never been very pleased with my results at painted furniture, so I'm asking here for some tips/advice on how to proceed, materials to use, etc.
All help will be much appreciated!
