Making user friendly interface

Well it depends on what you mean by user friendly. Yes, it is indeed possible, but then it depends on how you do it. If you use the WIN32 API, get ready to go through enough code to make you want to quit coding all together. You can use the console, or you can link your java. There are a few ways to do this. You could include the jar file and have that start up your program and just have batchfiles that run particular parts of your program and then display the result. Though i'm not sure how you'd transfer it from there to the java part.
