The usual way for a Cocoa application to know when everything is all set up is to implement the method applicationWillFinishLaunching or applicationDidFinishLaunching in the application delegate object.
The IDE itself is a Cocoa application. ccl:cocoa-ide;app-delegate.lisp is where the IDE implements these methods. Apart from loading the file home:ccl-ide-init, they don't really expose a way to run user-supplied functions. (This is probably a shortcoming of some sort; I'm not sure what the right answer is.)
You could modify those methods to call your function (or functions).
Mikel wrote a tutorial based on Apple's currency converter example. It's in the examples directory, and also at http://trac.clozure.com/ccl/wiki/AppleCurrencyConverter. It totally hides all IDE functionality, though.
