OpenChords is a guitar chord manager. It allows the user to present songs with guitar chords to a computer screen.

Doesn't write to the registry. Runs fine on a flash drive

Note: unfortunately it uses .NET framework 3.5

just saw the no .NET framework and java based apps requirement. Please ignore this post

Not using .NET or Java isn't exactly required here. If an application is unique enough, it may make it into the database regardless of the requirement.

There are programs in the database that require dotNET: http://www.portablefreeware.com/index.php?id=1564

Java-based apps are accepted if they work with jPortable http://www.portablefreeware.com/?id=1996 or, like XMind http://www.portablefreeware.com/index.php?id=1732, have their own included JRE.
