The more I use Eclipse, the more I understand it, and I learned how to run the Gradle test task through the IDE, so I guess never mind.

I might gonna have to get used to working with Java, Eclipse, and Gradle in the meantime. :/

I'm not really happy about this choice, since I've been working hard for quite some time, only to go back to the drawing board like 2 times already. But I don't think I really have a choice. I might gonna have to switch to Java just to continue on with my dream project, which kinda sucks imo.

I'm saying Swing is easy because it's already packaged with Java, so I don't need to focus on building anything from source. But what I do need to focus on is Gradle, a build tool that I'm not really familiar with. I'm also going to work with Eclipse, which isn't really friendly on Linux as well.

The reason why I'm thinking about this change is because I could not, for the life of it, build Qt5. I don't know why, but I just could not. That being said, I can't use Qt5 when it comes making GUI from Relaxian, my Pac-Man level editor. Swing is pretty much the easier choice imo.

I guess never mind, since nobody is answering this. :/
