Mountain Lion's Launchpad is pretty good but it's still hard to get something out of it after you put it in if you didn't get it at the Mac App Store. If Launchpad Control is overkill for you, this might help.
Drop one or more application icons onto an AppleScript droplet created from the script below to have those items' Launchpad entries eliminated. You can drag items or be prompted to select them when the AppleScript runs if you don't want to save it as an application. There is some error checking and information in the script. It doesn't do anything to the apps themselves.
You can test it on the app itself. In AppleScript Editor, save it as an app, drag the app's icon onto Launchpad, activate Launchpad, launch the app, then drag the app's icon into the window and press return when prompted.
