You can extract the tarball to a directory, then run mkfs.ext4 -d DIRECTORY FILENAME BLOCKS to create a filesystem[0]. You'll need to know how many blocks your filesystem needs to be in advance.
Unfortunately, mkfs.ext4 only works on Linux. There is no port for other operating systems.

If you want to create read-only, use ext2. No point in using ext4 if you don't want journaling.
Extents are a useful feature even for readonly although the gain is smaller.
You can also use ISO9660.
