I appreciate yours (and others) suggestions. I have actually worked through some wxErlang and agree that WxWidgets can produce a decent user interface but as you said there is a cliff there. I am trying to avoid getting bogged down in learning wxWidgets. My preference is a stand-alone application but it looks like that is not really going to be possible. My genetic programming code is in Erlang and I must say it was a joy to implement it there. Out of curiosity and for comparison of languages I implemented it in both C++ and Erlang at the same time. The Erlang was less effort to get right and ended up being a fraction of the code. The C++ version still has issues (memory issues mostly) and crashes more often than not. I had originally implemented it in C++ but after getting exposed to Erlang was convinced it would work better. As I said I implemented it in Erlang and re-implemented it in C++. Sure the C++ is faster but doesn’t work 100% yet. Erlang works wonderfully. A point to note here is that I have been working in C/C++ for both desktop and embedded development for 20+ years and was actually shocked that as a novice in Erlang I was able to implement it better there than in C++ where I am much more experienced.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'>Sorry for the digression.

I've been trying to keep the work totally in Erlang. Partly because I am trying to become better with Erlang itself and partly out of stubbornness. I had looked at using a browser based GUI but for what I'm doing I really don't want (or need) to be too complicated. One of the other responses suggested using C# to create the front end and communicate with Erlang via TCP. I had thought of that as well, but decided to pursue using pure Erlang but have become stymied by wxErlang and its difficulty.
