If you want as few Cygwin dependencies as possible...

...and all you really need to do is invoke a program, then I suggest
MinGW gcc (or Cygwin's old gcc-3 with '-mno-cygwin'). It provides a
non-Cygwin implementation of the standard C system() function. There
won't be any runtime dependencies except for dlls provided by the OS:

$cygcheck ./run_hello.exe

For fancier needs, consider the msw CreateProcess() system call.
