Does anyone remember Sun&#x27;s DevGuide app development platform?<p>I used this in the 90s, and it was ridiculously easy to get write an application. You visually designed your UI, generated code, and then added your actions&#x2F;event code. It  was straight forward.  I haven&#x27;t seen anything come close. Sure it was limited, but for the small apps I want to write for Mac and iOS, it would be perfect.
