This is indeed the best for this kind of tools.

You could use shell-command or shell-command-to-string,
or at a lower level, comint or processes (call-process or
start-process).
But you would just end up reproducing the features of compile.
Just customize:
compilation-error-regexp-alist
compilation-error-regexp-alist-alist
to teach compile the format of your messages.

Now, if your tool was interactive, then you would use comint to create
an interactive mode (like inferior-lisp, ruby-mode, maxima-mode, etc).
But this isn't the case, so just do M-x compile (or of course, you can
provide a specific command that calls compile with the right shell
command to invoke your tool).
