Is it possible to create a custom GUI in Java Swing? I’d like my application to be used on multiple operating systems, but I want it to have a custom and I don’t exactly know how to do it. Right now, I’m creating it using JLayeredPane and a bunch of JLabels with icons. It works fine right now, but I’m having trouble making the application resizable(I want it to get bigger so it will be better for larger monitors), and making a progress bar. I know the way I’m doing it is crazy inefficient, but I don’t know what else to do.
I’m also worried that by using so many images will slow down the application and possibly use more resources from the user’s device.
