Mod idea: Mushroom Tools?

So, I just started a new map and came up in a mushroom biome (seed = 5765650521366642658), but I forgot to set the mode to creative. Now sure, I could easily just remake the map in creative, but I had a better idea.

What if we could use giant mushroom parts as tools? They wouldn't be as strong as stone, or maybe they would be even weaker than wood, only to be used to get stone. But they'd work the exact same way as trees: their stalks act as wood blocks and with them you can make Mushroom Planks, Mushroom Sticks, and mushroom tools (but they would make a regular crafting table because a mushroom crafting table would be silly).

I have no idea how to mod on my own, so it'd be mighty fine if someone could help me out! :)
