This thing's fun - at Gardener's Supply: Kitchen Garden Planner.
It lets you input the dimensions of your own garden, has bunches of plants to drag and drop into the plan, and gives growing hints, when to plant stuff, I think in the order they need to go out.
I'm kinda dubious about their spacings, though, unless you've prepared the bed really, really well. And have lots of plant control devices and perfect trellises for everything, and prune them to death to stay in their appointed squares. My plan for my front 3x11' had a tomato, 2 peppers, 4 melons, 4 cucumbers, basil, dill, and God knows how many pole beans, peas, carrots, and radishes, with half the squares left over for flowers. In practice, well...
It's been my experience that that plot just isn't that big.
Interesting tidbit: they recommend you never fertilize peppers. I wonder why.
I seem to read all sorts of pepper-fertilizing strategies, just like tomato-pruning strategies. Fertilize on planting and never fertilize again. Fertilize every two weeks, but not when they're ripening. Water regularly, except when they're ripening.
The advice would make sense if you believed the peppers were putting all their energy into foliage instead of fruit (some plants do that...) But - they don't seem to. Foliage and fruit seem to be a package deal.

Thanks for that, some good information here.
Not sure why you would not fertilize? Makes no sense, you must feed the plants otherwise you'll end up with very small peppers.
