Application Icon Requirements

[Tom Cole]

Thanks to those who gave me information on icons. I'm striking out, 
though. I just want to make a little icon with an old paint program -- 
just something like a single letter or a little design. I don't want to 
buy a program for one icon, especially when I think it might be 
possible to do it more simply. I've made some little graphics,, but I 
put them into the Standalone Applications Settings in Studio, I get a 
message that a large number of required  things are missing. What is a 
simple way to make a modest little icon with a paint program and gif 
converter and make it work?

Thanks!
Tom
