The way the first one works is that it's a web page that grabs the card popups from X to Y and then displays them in the same page using iframes. It's using PHP so you need a server with PHP to run it on (there are a bunch of free hosts so this is no prob).
Making an exe is too much work, and means the user would have to download it. Making a site and just hosting it is much easier.
Now that I think about it, I think I'll go and do just that. Brb, version 3 coming in 10 minutes.
EDIT: blargh forgot I can't access my host from here
