The isCOBOL IDE is capable to allow you design and generate fully graphical Screen Programs, by using a WYSIWYG Screen Editor and several other content editors (Working Storage, File Section, etc.).
This tool is a very comprehensive one to help you to quickly design and produce fully functional Graphical Screen Programs that run not only on Windows but on any GUI capable workstation (Mac, Linux, etc.) as long as a JVM is properly installed on it, although the clients on a distributed installation are usually Windows while the Server can be anything else (Windows server, Linux, Unix, etc.).
