There are two versions of GPG.  One, the 1.4.x line is a self- 
contained GPG that builds on many platforms.  It only does OpenPGP.   
The other, 2.x line, is a more modular version that builds on fewer  
(but still all of the common) platforms.  It uses libraries for its  
crypto and other things, and is somewhat harder to build.  It does  
OpenPGP and x509 and has some other nice features that aren't in 1.4.x.

Of course, when you download a prebuilt binary, you don't need to  
worry about building it.

I wonder if you are thinking of Windows Privacy Tray?
Or possibly GPGShell?
