Poplar is really bad outside.

White oak (but not red) is excellent, and pine is decent. Cedar is
very decay resistant, but soft, so it's less suitable for thin parts..
Some lumber dealers can get lower grades of white oak for very
reasonable prices. It's used for truck decking, durable pallets, and
old-school exterior trim. If the windows are going to be removed and
replaced as seasons change, handled often, or have thin structural
parts, I'd look into white oak.
