No, gparted does not work in this case (but in most other cases gparted is a good tool).

But you can mount the partition with the iso9660 file system manually, and after that you can look at it with a file manager, or as illustrated below, with command line tools. For example, I can read the file README.diskdefines in the iso9660 file system. Try it :-)
