Various methods for doing this were described in the recent thread: http://www.sawmillcreek.org/showthread.php?t=29282
This week I replaced two bottom cupboards in our kitchen with four drawers. I built the drawers out of 12mm Baltic birch and the false fronts were made out of ¾ inch poplar. Pocket hold joints were used throughout.
The late Danny Proulx describes an easy and almost foolproof method for attaching door fronts and I took pictures of the steps.
(1) The cupboards with doors removed and dividers and drawer sliders installed.

(2) The 4 drawers painted and installed without their false fronts.

(3) The four false fronts have been painted and a hole has been drilled into each in the ultimate position of the knob. A temporary ledge is clamped below the two bottom drawers.

(4) With one false front resting on the ledge, a large flat head screw is driven through the pre drilled hole into the drawer behind.

(5) Making sure that the door is level, drive the screw the rest of the way in.
