GZipper is a drag-and-drop program that gzips any files dropped onto it. If a file is already gzipped, it will gunzip it for you.
Drag a file onto it, and it will be gzipped using the highest level of compression available from the gzip program built into OS X. (Unfortunately, folders and packages cannot be gzipped unless the "Recursive" function is on.) If the file is already gzipped, it will be unzipped.
If you open the program by double-clicking it in the Finder, you can set the preferences in the main window to overwrite existing files and/or operate recursively on directories.
