I never understood the need to "emulate" all of them. Linux has always been a mess of tools written against different UI styles ( GNOME, KDE, MOTIF, ... ), Microsoft also reinvents its UI with every release leading to outdated application UIs and I don't know how consistent Apple was. I think the best you can do is choose one and stick with it, its not like most websites look and feel native.
