minimum framing for deck?

[optionguru]

I'm looking to put in a very basic 16 x 16 freestanding deck / platform at my camp.  It will just be a nice level area to put a picnic table on and set up the camp stove.  The ground is damp so I figured I would dig some holes and use 12 inch sonatubes and connect to 4x4's.  How many footings do you think I need, this won't be supporting much weight, other than me  How would you frame it?

I should add that I've built a few decks and I think I tend to overbuild them, so I'm really looking for some best practices type of information.

Thanks,
Peter
