Check out the new MSPaintIDE on GitHub.
A video of it demonstrates creating a simple "hello world" type application. About one minute later in the video, you can see how easy it is to create a small GUI application that pops up a simple dialog box.
MS Paint brings unique advantages as a source code editor for Java. You can erase source code you no longer want. You can re-arrange source code. Correct mistakes. Etc.
Then the IDE (integrated development environment) can then OCR your code, update your project tree, compile, and produce a completed executable build. Try doing that with a stupid ordinary plain ol' text editor!

You've missed the killer app for this new IDE. Copy-and-pasting answers from Stack overflow is just too hard. Now you can screenshot them and drop them directly in the IDE.
Can we get integration with the new Win-Shift-S snipping tool?
:D
