If you set `org-file-apps' in your init file via setq you can use

(setq org-file-apps
      `(("\\.jnt\\'" . ,(format "%s %%s" (w32-short-file-name "C:\\Program Files\\Windows Journal\\Journal.exe")))))

Cf. http://www.gnu.org/s/emacs/manual/html_node/elisp/Backquote.html

Not sure.  Maybe you could perform the translation with a translation

C-h v org-link-translation-function RET

,----[ *Help* ]
| org-link-translation-function is a variable defined in `org.el'.
| Its value is nil
|   This variable is potentially risky when used as a file local variable.
| Documentation:
| Function to translate links with different syntax to Org syntax.
| This can be used to translate links created for example by the Planner
| or emacs-wiki packages to Org syntax.
| The function must accept two parameters, a TYPE containing the link
| protocol name like "rmail" or "gnus" as a string, and the linked path,
| which is everything after the link protocol.  It should return a cons
| with possibly modified values of type and path.
| Org contains a function for this, so if you set this variable to
| `org-translate-link-from-planner', you should be able follow many
| links created by planner.
| You can customize this variable.
