For individuals who do not like command prompt, you can use a GUI tool to handle your NAnt build files. This was mentioned on the Alt.NET yahoo group. Check it out here. I just played with it briefly and it does it’s job. You are able to also run the build file while in the UI and see the output. I’m a command-line guy so, I will probably be using for educating other developers on NAnt. It’s a good starting point. It will get people up and running fast.
NOTE: If you are going to .NET 2.0 related items with your build file, you need to edit the config file (NAnt-Gui.exe.config) in the bin folder. Look at the very bottom of the file and un-comment the 2.0 runtime lines (just like the NAnt.config files too):
   1: <startup>
   2:         <!-- .NET Framework 2.0 -->
   3:         <supportedRuntime version="v2.0.50727" />  <!-- The line I needed -->
   4:         <!-- .NET Framework 2.0 Beta 2 -->
   5:         <supportedRuntime version="v2.0.50215" />
   6:         <!-- .NET Framework 2.0 Beta 1 -->
   7:         <supportedRuntime version="v2.0.40607" />
   8:         <!-- .NET Framework 1.1 -->
   9:         <supportedRuntime version="v1.1.4322" />
  10:         <!-- .NET Framework 1.0 -->
  11:         <supportedRuntime version="v1.0.3705" />
  12:     </startup>
