Saw a couple of people discussing JavaFX here. I started Java a couple of months ago and made a Tutorial on JavaFX if anyone's interested.

Here's a link:

Got a few good tutorials here that I'm sure will come in handy.

A Full Tutorial on Python Tkinter discussing each widget individually, complete with bonus content -> https://coderslegacy.com/python/python-gui/
There's also another GUI tutorial, based on another GUI library PyQt5 -> https://coderslegacy.com/python/pyqt5-tutorial/

Game development with pygame -> https://coderslegacy.com/python/python-pygame-tutorial/

A compilation of tutorial on all the major libraries in Python -> https://coderslegacy.com/python/libraries-in-python/

I first got interested when I was introduced to the programming software for kids "Scratch" at School. Long story short, I was hooked. After mastering scratch I moved up and began learning Python. The rest is history.

I've developed my own tutorial site here at https://coderslegacy.com/ where I teach Python and several other languages.

I think Python is a pretty great choice for beginners. I started out with it myself and have had great success with it and other languages I picked up later. There's this Python tutorial which is divided into three parts based on difficulty, which I highly recommend. Here's a link to it.

Here is another post that discusses several popular programming languages in detail, and which to pick.
