Forgive me if I've got this wrong... but I'm guessing that the way you've asked your question makes it sound like you may think geotargeting is to provide a wish list of the countries you wish to rank in, rather than to make sure that your country-specific content is channeled to the appropriate geo-area.
Note that Google prefers to favor an actual local presence. As mentioned, country-coded TLDs are the best way of reflecting that. Subdirectories or subdomains might also work... but they're more for language-related content than for country-specific presence. You can also set preferences for a .com to target a specific country, but that's not a multi-country solution.
If you've got nothing to put into the subdirectories, it may be that you're not understanding what geotargeting is for.
