2 ways are easily available depending upon the size of Your Flash Drive.
 You could use GPG2GO and do everything from the Command Line or You
could simply Copy Your GnuPG Directory/Folder to the Flash Drive and
then use the GPGshell Portable Utility [located at the bottom of the
Start Menu list] and then run with a GUI.

How secure is Your passphrase?

Robert already covered the issues involved in using an untrusted PC.
Also keep in mind that not having control over the PC also means no
Control over the Swap File, whether or not any Keyloggers are present,
etc.  Another consideration is that many Public PC's have the ability to
launch any .exe File blocked.  This is particularly true in Library's
and other places where there is a concern that Students will attempt to
install malware, etc.

If You are just going to be using the USB Drive for Email then there are
Applications like Mobility Email & Portable Thunderbird w/Enigmail + GnuPG.
