Making an EnergyStorage when clicked open an Inventory

So I have a simple EnergyStorage, I have a GUI, but how would I make the player open the GUI?

Also how would I make a TileEntity/EnergyStorage that transfers energy?

I would provide code but it's so simple. I have not used ForgeEnergy yet sorry.

Also would I register the EnergyStorage block like a TileEntity or a Block or what method would I use?

Sorry about this being so short with so many questions, there is so little documentation about ForgeEnergy.
