In the case of Ghostscript it is actually quite complicated. I have code 
for finding Ghostscript in the file w32-regdat.el which is part of 
EmacsW32. This uses an external program to read the Registry. The actual 
Registry interface is in w32-reg-iface.el (also in EmacsW32).

It is quite much code to put here on the list. If this is interesting 
for the arguments here then maybe you could look in the zip file found here:

Finding GSview is in contrast very simple since it is in App Paths.
