Easy to Make Trellises for Pole Beans?

I want to make an easy trellis for pole beans. Does anyone have any ideas on how to do that? Also, I need to make supports for zucchini squash. I have heard that you can use tomato cages for this. Will this work? What are some cold weather crops I can plant now that will be able to harvest early. I live in southeastern Michigan. I am planning on planting, radishes, carrots, and lettuce, but I have another good spot that gets lots of sun on the south side of the house and would like to plant another cold crop in that spot. Is there one that will work in that area?
