one last time

I apologize for bugging the members of this list...  I will only ask 
this one last time.

I have been programming with MacPerl for a while now and have 
developed some fairly large programs.  I wanted to try developing 
some user interactive (graphical) applications and would like to find 
some examples of code that would help me get started.  Now I looked 
at the code samples that folks previously pointed me at but.... 
those are very sophisticated, and complex, and specifically, 
un-documented.  With no comments its pretty hard trying to figure out 
what I need to do to get something written.  Chris's Calculator 
program, and Kevin Reid's Chaser program are super examples, but with 
almost no explanation of what is for what.  (BTW, I tried sending an 
e-mail to Kevin Reid's e-mail address given in the code but the mail 
bounced with a host unknown error).

In any case, I know I'm opening myself up to possible flames, etc., but...
does anyone have an example (that is the equivalent of a "Hello 
World" program) that shows the beginning steps required to get 
started with a GUI MacPerl app?  Something that just displays an 
image and then perhaps does something else if the user 'clicks' on 
the picture.

Anyway, I appreciate the help/advice/comments/criticisms/etc.
