I'm very interested to hear more about your book. Do you also have an
English translation?
For a while now I've had the idea of writing a Sugar activity for the
One Laptop Per Child project, that would teach kids how to code in
Python, without assuming that they know anything at all about
computers.
There are lots of coding tutorials, even lots of Python tutorials, but
almost all of them assume that one already knows some other language -
and that one is a grownup.

I think you could write a simple AppleScript that would do the same
thing as that shell script. AppleScript have icons that are more
harmonious with the Mac experience.
Alternatively you could write a very simple C program that you build
with Xcode as a Mac application (a ".app" application bundle). It
would launch idle the way you want it and then quit. It would look
just like any regular Mac OS X application and could even have a fancy
icon.
This program would use either the execve system call or the system
library function to actually do the launch. Reaching the end of main
after doing so would cleanly quit the launcher.
See "man execve" and "man system".
The difference is that execve launches a program directly, whereas
system launches a shell that then executes the command line you feed
it.
