I have one in MissingH, and it's written in pure Haskell.  Reference at
http://quux.org/devel/missingh/html/MissingH.Cmd.html, code at

If you choose to not use that code, and instead write your own, just
know that popen() can be implemented in terms of pipe(), dup(), and
fork() in C -- or createPipe, dupTo, and forkProcess in Haskell.  Take
care to handle SIGCHLD properly -- or, just use my module :-)
