If you are not keen on having to sink deadmen to anchor wires or end brace assemblies, I have seen concrete mesh and cattle panels mounted on posts used to good effect. The concrete mesh can be formed into an arch.
I picked up a trailer load of 10 by 4.5 foot galvanized fence panels (1/4 inch vertical wires, 1 inch square tube steel rails) when the pool fencing laws changed here. In the summer I set them up on frames to grow gourds, cucumbers and beans. The fruit hang down for easy picking and they are easy to take down at the end of the season to tear off all the old vines and store flat. That way I can do crop rotation in the veggie patch. I find these temporary trellises easier for annuals.
But if you have the space an overhead wire trellis like mike mentioned is easier for perennial things like grapes and passionfruit where pruning is required to keep old unproductive wood to a minimum. It just gets too hard to try and pull long vines through mesh openings overhead. We had alot of grapes growing up and pruning them on an arbour was a nightmare. If you build a wire trellis have a look at the gripple viticulture fittings. The gripple patent has expired so you can find generics that are less pricey, and they will save a ton of time tying, tightening and adjusting wire. If you go with wire if is probably best to use medium tensile wire for any lengths less than 50 yards.
