Build me a simple beginner friendly Web3 app that lets someone connect their MetaMask wallet, send ETH to a smart contract, check the contract balance, and withdraw funds from it.

I want it to feel like a clean single page demo, with a basic frontend and clear buttons or inputs for each action. Use the existing contract interaction setup with viem, and make it work well for a local Anvil chain too. Keep the UI easy to understand, with helpful status messages for things like connected wallet, transaction progress, success, and errors.

If you need current setup details, look up the latest docs online and make sure everything runs smoothly. I’d like the app to be simple enough for a beginner to learn from, but complete enough that I can connect a wallet, fund the contract, inspect its balance, and withdraw from it without extra hassle.
