Launch page with multiple buttons

Is it at all possible to make a launch page with several links which all open a different course, utilising the script from launcher.html?

I'd like to have a page that looks something like this, but then have each link open in a new window, exactly like launcher.html does.

Looking at the code, the only possibility I see now is to add that entire script to each link, but to give the function a different name for each link ("LaunchContent1()", "LaunchContent2()", etc).

I can't imagine there isn't a better option, but this script way surpasses my knowledge, so any help will be greatly appreciated :)
