"Can anyone help me out with the simplest way to make a compost pile for my garden"
Put ANY kind of plant matter in a big pile. You will have only about 1/20th or less (by volume) the amount of compost relative to the amount of plant matter you start with, so start with LOTS. Let it sit for a few weeks, keeping it nice and moist (but not TOO moist). Turn and mix with a pitch fork. After it composts for another few weeks you will need a (stronger) garden fork to turn and mix it.
I just transfer the whole pile to another spot next to the first pile, making a "secon" pile out the the material of the first pile. That seems to involve enough "mixing." Start with the top of the first pile and put it on the bottom of a new pile, then work your way down until the bottom of the first pile is on top of the new pile. Then a few weeks later transfer the second pile back to where the "first" pile was.
While chicken wire or welded wire is nice, to keep things from blowing away, you can also simply dump soil or finished compost, or partially finished compost, on top of your wind-susceptible stuff, to keep it from blowing away. Withing a few weeks, it will be broken down enough so that it won't blow away in normal winds.
While ANY kind of plant matter will do, it is best to have a mix -- the ratio is not extremely important -- of browns and greens. Greens have more nitrogen, browns help the texture I think, and prevent the pile from developing an unpleasant smell. Don't use excessive amounts of juicy fruit. For example apple cores. Melon rinds. Whole peaches. Modest amounts of canteloupe rinds are fine. Leave out peach pits. Apple peelings should be fine. Banana peels are Excellent.
