You can probably do a "true" pure C application (as in no Cocoa at all and no linking to objc-runtime) by dropping down to the CoreGraphics layer, but a lot of it is undocumented.

There's also Carbon (which I always assumed directly hit the same underlying quartz apis), but that's long deprecated and iirc never supported the UI portions in 64-bit
