Do any osdevers using OSX know of a replacement for the grub tools for programatically creating disk images for qemu/bochs?

The quick and dirty way on any non-linux OS is to grab an existing image from somewhere, clear the owner's files from it, and then save that image with your project so you can use it as a base to construct the rest of your harddisk from it later in a similar fashion.

The advantage of this is that you only need one tool: something that can read and write the filesystem - for FAT systems, mtools is a portable tool that does exactly that.

I made a shell script that compiles my OS and turns it into a bootable iso with GRUB. It's pretty well commented, so just take out the part that is helpful to you! Best of luck!
