Here's a Windows Namecoin GUI for managing your wallet and domain names. It also allows you to manage your bitcoin wallet as well. Switching between namecoin and bitcoin is as simple as clicking Tools -> Switch to, then choosing either Bitcoin or Namecoin. It's written in C# and requires the Microsoft .NET Framework 4. Let me know of any features you'd like to see implemented and of course, any bugs you come across.
If you are not interested in using it for bitcoin, just leave the bitcoind path empty. http://i.imgur.com/UQw3w.png
