Stand up a Kubuntu Rust development environment from scratch — install rustup and the toolchain, switch from Bash to Zsh, and configure Kate with an embedded terminal for tight edit/build cycles. Then implement the iced Sandbox trait to write a Hello World and a counter button that updates state in response to messages.

Build a 150-line iced calculator with a state struct, a message enum, and a view function — then add unit tests that exercise the calculator's update logic without launching a window. Walk through the core iced widgets (button, text, column, row, container) and modify each to extend the calculator's behavior.

Extend the iced patterns from Week 3 into a list-driven application. Back the to-do list with a Vec of TodoItem values in state, wire up the iced text_input widget for new-item entry, and route per-row toggle and delete actions through the message enum so each item mutates independently.

Walk through the official FLTK Pong example, then extend it across four iterations: add a pause button that halts the game loop, a slider that varies paddle speed at runtime, and a high-score file written to disk between sessions. Each step is a concrete state-and-message extension to a working game.

Build a GTK4 password generator using the gtk4 crate's ApplicationWindow, Entry, and Button widgets, with the rand crate generating random ASCII characters. Add a ToggleButton that flips the Entry's visibility property to mask or reveal the generated password.

Build a Simon Says game with relm4 — a Rust GUI framework that layers an ELM-style Component trait on top of GTK4. Lay out four colored buttons in a 2 by 2 grid, then add a Vec of Color values as the sequence and a playback timer that lights each button in turn before the player has to repeat the pattern.

Build a quiz application in egui — an immediate-mode framework where the entire UI is redrawn every frame from current state. Define a Question struct, run a frame-counted timer that ticks down each draw, and accumulate a score across a multi-question quiz with a restart flow at the end.

Compare iced, egui, GTK4, FLTK, and relm4 head-to-head — ergonomics, platform reach, async story, theming. Add provable contracts to GUI state with the assert_invariant macro so impossible UI states fail loudly at runtime, then ship a release with cargo-dist for cross-platform binaries, Flatpak for sandboxed Linux, and AppImage for portable distribution.

A culminating practice assignment that synthesizes every framework and pattern from Weeks 1 through 9 into one shippable desktop application.
