Add NiceGUI to GUI Development section

[Rinzlov]

I have tested a few of the GUI frameworks listed here and NiceGUI definitely deserves to be on this list!

What is this Python project?

Describe features.

• Very easy to create simple apps with rich interfaces, using predefined elements (opinionated in terms of style etc).
• Good for advanced use cases as well, I use it professionally and ditched other libraries since they had more bugs and less features.
• Declarative style possible, similar to React.
• Possibility to use CSS, Tailwind etc out of the box.
• Baked-in solutions for timers, storage (local, browser, tab, session, server) and many more.
• Seems quite stable and with less quirks than other libs I used like Kivy.
• A big set of pre-defined element with many styling options - based on Quasar library. This is just a few points from the top of my head but if you ever need to create python GUIs then I strongly recommend checking this lib out. I always considered GUIs to be Python's week side so I was really happy when I discovered NiceGUI two years ago.

What's the difference between this Python project and similar ones?

Enumerate comparisons.

• Using CSS instead of custom layouting strategies, this is a massive win due to popularity and stability.
• As mentioned - rich element library.
• Vast range of use cases covered since it can be run locally, from a server or made into a desktop app and shipped as .exe. --
