Mentoring needed with raspberry pi 3 B+

I am a fledgling programmer and I just need a bit of help with a project I am working on.

I will be writing some applications where I will be creating GUI's, communicating with the GPIO pins and will need to display videos as part of the process.

I can use Java/Swing or Python/Tkinter – whichever will work the best. I would also like to use VLC media player since it's already loaded on there.

I just need help/guidance with a couple of things:

– I would like to have the option of using Java/Swing. I have programmed using Java on there before but it seems like the only way to access the GPIO pins is through a library called pi4j. When I try and access it I get an error saying it's the wrong hardware. online I have read that it's fixable by re-installing it using a type of file I am unfamiliar with and would like some guidance so I con't screw anything up. that should be a quick fix.

– I also need to be able to access video from either Java or Python – preferably both. But when I try and import vlc, which is installed and should be there, it says it doesn't exist. I think it's in with the Python 2.7 files instead of the 3.0 files and need to get that figured out.

Also if there is an easy way to do that within Java I'd like to learn of it.

So what I am asking for is someone who speaks English well and can teach me – not just do it for me.

Thanks,

Larry
