I also thought about this some time ago. My quick and dirt solution was using
array as line buffers, and display visible lines in a multi-line text box. Its
main drawback is no syntax coloring.
An open J code solution is to use isigraph and gl2 command. it should be capable
of doing everything you wanted except unsupported mousewheel event.
I would not recommand richedit because rtf is a rather strange format, does not
support unicode and is window specific.
