A plugin to infinitely stock chests?

Hi.

I'm running a multi-world server including a PVP world with an arena, I need certain chests infinitely stocked with certain items...

I don't wanta have to go installing massive plugins to do this, I just want chests, nothing else.
I also need more then 1 item to be stocking the chest, like 1 row, iron sword, second row, diamond sword, etc.

Ideas?

Thanks in advance,
Darkedge.
