With TclTkAqua, you can now build a complete GUI in a portable scripting language, and have the application run the same way on Windows, UNIX, Mac OS X, and Mac OS 9... but with the native look and feel of each operating system and using native buttons and controls.

If you're working in a multiplatform environment, this is no small advantage.
