Divorced Ruby (only thing she has is her beauty)

Married Java(powerful but hard to cope up with)

In love with Python (Powerful and beautiful)

Have a crush on Kotlin (She is something else, sadly she is Java's friend)

In an Affair with C# (Like java but easier to deal with)
😂😂

#Love gone wrong 😝

(Just a joke try to see the humor in it. Don't get offended 😂. Thank you. )

I started with C#at the age of 12, it was way too complicated and I learned Lua for Computer craft instead. Next I learned Ruby for RPG Maker and finally Javascript for web Dev stuff.
Now comfortable enought with Javascript but put off by its quirks I learned Java for compiling faulty minecraft mods, but I only fully learned it in school.
At the same time I learned python and quite liked it for scripting, but ultimately it was not a good match for my projects.
Disapointed with Java I returned to C# and liked it quite a lot, but started learning C++. After touching my first Microcontroller I learned C and I've stuck with it as my favorite language.
Along the way I picked up Kotlin, in case I need to do some Java shit. Much better.
But how did I come to an understanding of programming. Well I got better after each time I got a layer deeper until I hit silicon.
I had tinkered with electronics since I was 15 so I just had to study some boolean mathematics in school and some vintage computers architecture and instruction sets and...
Then I finally understood how that shit I wrote in Lua way back when was actually executed by my hardware.

Allways dig deeper and you'll find enlightenment eventually.

I don't get it.
I tried Kotlin on Android just for fun, and it doesn't support binary data handling, not even unsigned types until the newest version. Java suffers from the same disease.
How does one parse and process binary data streams on such a high end system? Not everything is highlevel XML or JSON today.

And it's not only an Android issue.
Python has some support for binary data, and it's powerful, but not comfortable.
I tried Ruby, Groovy, TCL, Perl and Lua, and only Lua let's you access data directly without unnecessary overhead.
C# is also akward when it comes to data types less than the processer register width.

How hard can it be to access and manipulate data in its natural and purest form?
Why do the so called modern programming language ignore this simple aspect that is needed on an everyday basis?

Ok so guys, I really love back-end, but sometimes I'd like to do a complete software to show off to friends in my free time, So question:

What programming language should I learn to make gui softwares?

I don’t want them to be pieces of art, just functional and with not too man " unintentional features".

I really love Python, but for gui heard it's meh, but may be wrong

I don't want web technologies

looking forward to learning C, but not necessarily for gui
could try c++ I guess

Don’t want .net (coz you know ms and their Java knockoff)

Ruby seems cool, but it seems to be annihilated by ruby on rails

Not Java but Kotlin seems really cool, could also go with scala, idk

Forgot the other things
