The Acrobat SDK is mainly the documentation you need to work with Acrobat, plus sample programs. You can then either insert the JavaScript program into your PDF using Acobat, or (as you will probably do in this case) write a folder level script that would add a menu item or a tool in the Tools panel to in any text editor and save it in one of Acrobat's JavaScript directories.
You can also execute JavaScript in the JS console, but again, the documentation in the SDK will talk about all this. You can find the SDK here: http://www.adobe.com/devnet/acrobat.html
