Yesterday, I installed GPGMail on my Mac and had it generate a keypair, and the procedure was actually rather pleasant and clear. I did not know yet about this master- and subkey scenario, and the setup wizard did not offer this option, but I think the UI could be extended to support this without too much extra hassle.
