I believe OP's project is just doing some lightweight "make it executable" bits but the actual JediTerm that it is using for the "terminal" part is, itself, on Swing/AWT https://github.com/JetBrains/jediterm/blob/4cef2840aed5ec1d6...

Although, interestingly, while digging up that link I noticed the JediTermMain that for sure makes it plausibly executable so I dunno if OP's project is actually just "for funzies" or if there's otherwise something added https://github.com/JetBrains/jediterm/blob/4cef2840aed5ec1d6...
