Best Language & Framework for GUI development

[47]

Hello, I am looking to make a GUI application for desktop, I want it to be lightweight as it will be running during resource intensive tasks like video rendering etcThese are my requirements - Lightweight, shouldn't be resource heavy: below (75 MB Ram) and low CPU & GPU preferably
- Language shouldn't have a massive learning curve/ super esoteric
- A GUI Desktop app
- Possible to make minimalistic but nice looking UI
- Frontend and backend same language
- Supports cross-platform (Optional)
Thank you for reading my post :)

Those are some strict requirements.
If you want It to be lightweight, you gonna have to go with C/C++. QT is a good framework for C++. For even less ram usage, nuklear/xlib is an option for C.
There is a steep learning curve for QT and C++ depending on your background. If It is too complicated for you, try electron with JS.
