From the developer:
NouveauPG is the result of almost two years of research, design, and development of a PGP client that was accessible to less technical users that desire strong encryption.
Every inconsequential option has been removed from the user interface and only information that is actually needed to verify the validity of a public key certificate is displayed.
You may want to check out more Mac applications, such as TelnetLauncher, Password Manager or Tiptoe, which might be related to NouveauPG.
