Looking for a resource

I'm just getting started with modding and am interested in creating a block that is a mixture of a furnace/crafting table. It will burn fuel (coal or wood), like a furnace and have a crafting grid like a table. I know that there are things like the Alloy Furnace from RedPower 2 that do things like this so I know it's possible. Can anyone point me to some instructions/demos of how one would create a block like this, i.e., custom GUI when clicked, shaped recipes, etc. I'm looking at the code for various blocks that do things like this but I would really like to know exactly what/why things need to be done so that I can maintain/update whatever code I write.
