Short Answer: No.

Although you can compile statically most of the libs, cygwin1.dll is
not possible to include in the executable. There are technical
reasons, and also licencing reasons. Please see:

You don't need necessarily to distribute the setup.exe, or build a
cygwin package. You can do as probably you already are doing: "gather"
the needed Dll's (only those specific to Cygwin, of course), join the
.exe, and include the source, (as this is required by the licencing),
and just drop it together in a directory on the client PC's.
