Here is an easy way to do this. IF you are pretty new to wood, then I would only recommend dado'ing our the joints shown as the red arrow. The rest can be butt joints the little box is a side view of a piece of wood. The blue line represents the (pocket hole jig) pilot hole and screw that would be used along with glue to assemble the rest. This was you really on notching 4 joints the rest I would just use the pocket hole jig to pilot the holes and use the screws that are meant for that type of joint. You can make a very nice cabinet as long as your cuts are accurate and straight & perpendicular.
