You may wish to investigate "Model-view-controller"
http://en.wikipedia.org/wiki/Model-view-controller.  It sounds like this is

keyword to run searchs for alternatives to model-view-controller.

Also, note that the Drscheme GUI builder allows the builders GUI
representations to be inline, so you can put pieces anywhere you want.
