You really need a structural engineer to figure this out for you, but
I think your first assumption of a 4" steel pole with 3' in-ground is
much too flimsy. I would start thinking in terms of a large I-beam
buried in a 3x3x6' deep hole with concrete and rebar. Slice the top of
the I beam at a 45 degree angle, drill three holes in it, and put one
guy through each hole with suitable hardware. If it is possible to
avoid using elevated guys, choose that method, at the expense of some
inconvenience walking around the yard.
