git itself supports this sort of functionality via -C, as does GNU
tar, which suggests such an option in gitk should be named -C, as
well.

Taking git's -C documentation as a template, perhaps this could be
written instead as:

    Run as if gitk was started in '<path>' instead of the current
    working directory. When multiple `-C` options are given, each
    subsequent non-absolute `-C <path>` is interpreted relative to
    the preceding `-C <path>`.

This description correctly reflects your implementation which allows
--cwd to be specified multiple times.
