What language should I code my software in ?

Hey guys !

So, quick backstory, 15 years ago I learned C just for the kicks of it. Massed around with it for a bit, tried learning C++ after but some issues never had me finishing that up.

Now, I want to code a (very) basic software to stream with. Imagine it as a DeathCounter, but for shiny hunting in Pokémon.

Problem is, I don't know what language to code that in. I need a good GUI to capture and put on my stream, with a few images/GIFs put in a certain spot, a counter function and basically a few dropdown lists that help me chose certain functionnalities, like modify certain settings to change odds, stuff like that.

I did a quick software 2 years ago for a pen&paper game, which is just a basic GUI with cases to check so they light up and give a better idea of the result you gotta have with your dice. I did this in C# via Visual Studio, but it went kinda bad I'd say lmao

So, do you guys have any suggestions for me ? I know there's like a million different languages with each their own strenghts and weaknesses, but I don't wanna spend a lot of time I already don't have to find myself unable to do what I actually want. So, any suggestion is really appreciated ! Thanks a lot
