The right editor is the one you prefer. Personally I'm unable to
code in anything but emacs, but the path was stony and I often
wish I'd be more comfortable in less "heavy" editors (I try to
use pico, but only for quick editing jobs - in the end I always
go back to emacs).

You should look at `handle-exceptions' and `condition-case':

(condition-case <expression>
 (ex (i/o) <do something>) )
