Windows GUI recommendation for USB disk

[Robert Eden]

I'd like to place a static windows GUI executable on a USB disk to

encourage folks to encrypt data while using snail-mail.



I don't want windows shell extensions as that would require an installer

(WinPT ).



I'm thinking just a single EXE that provides a simple GUI and supports

symmetric keys...



I don't know if GPA does this, I've been having trouble getting it to

compile on my cygwin install. (The README talks about a pre-built

binary, but it doesn't exist)



Any recommendations?
