Show HN: New Python GUI Framework (better than others?)

Hey HN,

I built [*WinUp*](https://github.com/mebaadwaheed/winup) — a modern GUI framework for Python that works like React or Flutter, but with native Qt widgets under the hood.

### Why I made this: Python has great libraries for data, backend, scripting… but most GUI libraries are either: - Verbose (Tkinter, PyQt) - Old-school imperative - Slow or bloated (Electron)

WinUp gives you: - Declarative UI with `@component` functions - Hot reload for real-time editing - CSS-like styling system - State binding with `State()` like React - Native rendering via PySide6

### Example: ```python import winup from winup import ui

def App(): # 1. Create a state object with an initial value. counter = winup.state.create("counter", 0)

    # 2. Create the UI widgets.
    label = ui.Label() 

    # 3. Bind the state to the label's 'text' property.
    # The lambda function will re-run whenever the counter changes.
    counter.bind_to(label, 'text', lambda c: f"Counter Value: {c}")

    def increment():
        # 4. Use the state object's methods to update the value.
        counter.set(counter.get() + 1)

    return ui.Column(children=[
        label,
        ui.Button("Increment", on_click=increment)
    ])
if __name__ == "__main__": winup.run(main_component_path="file_name:App", title="New State Demo") ```
