Spectra (formerly WinDOS) is a GUI Shell for DOS. It is authored by Denis Andrianov.
Almost Fully Supported in DOSBox 0.72.
Making it work
It works just as it would in dos. You must change to the directory it is installed in to run it. To use the Desktop, unzip the plugin to the same location as installed directory. To use the features of PKzip within this, move the installer into the Archives directory within the install directory and run the install program.
