On macOS, they're the standard "traffic light" buttons on the left; on Windows and Linux, line/box/X in the upper right. Users are familiar with these controls and they're standard on desktop apps. Red and X would close the window, but the app would continue to run in the background, and be reachable to the user from the menu bar icon (macOS) and taskbar notification area (Windows).
Maximize (yellow, box) won't be available until later when we do a sizable window, and can be omitted or ghosted-out.
