Convert Simple C# Application to Java -- 2

We have a small C# Windows Application that we would like to convert to Java. It doesn't have to look exactly the same, but it should look and work fairly similar and follow the same structure/architecture on the back end. The Java GUI should also look up-to-date. The C# application essentially uses a file reader to access a text/csv file, iterates through every record in the file, map each column of the input file to different web service APIs, send the information to the web service, and store the results to the defined output text/csv file destination. This is all done through a simple GUI. This is a small to medium size project. C# Project Attached. - Must be able to create a Java Based GUI - Must know how to make Web Service API Call (REST/JSON) - Must know C# Forms Application The C# Project can be found here: [login to view URL]
