Wolverine was a GUI-based off-line mail reader for FidoNet-style networks that I developed back in 1996. It was compatible with BlueWave and very similar in functionality, albeit with a modern-looking GUI interface. It supported BlueWave & QWK formats. It hasn't been developed since 1997, I think, but I'm providing the source code to provide insight on app development practices back in the 90's.

It used FatalVision GUI library which also I was one of the two developers of.

To see how it works you can try out a working version on DosBox
