ssh myname@myhost "sg mygroup -c 'myprog ...'"

should work.  The key is you need to preserve the inner quotes long enough
to pass them along through the ssh to the remote shell.  In all the tries
you showed here, your quotes are stripped out by the local shell.  You need
a second set of quotes, or you need to escape the quotes with backslashes,
to keep them around long enough.
