I need a lightweight notepad application that lets users type plain text and reliably save or reopen their work later. No rich-text bells and whistles—just classic, distraction-free typing with the usual Cut / Copy / Paste and Undo / Redo. You’re free to choose the tech stack and operating system you’re most comfortable with; Win32, Qt, JavaFX, Electron, Python (Tkinter or PySimpleGUI) or something similar all work for me as long as the final build launches quickly and feels native on its target platform. Deliverables • Compiled app or runnable script for the chosen platform • Well-commented source code • Short README covering build steps and basic usage Acceptance criteria • User can type, edit, and navigate plain text • “Save” and “Save As” write standard .txt files • “Open” correctly loads existing .txt files without corruption • Interface stays strictly plain text—no formatting or syntax highlighting If this sounds straightforward for you, just tell me which toolkit you’ll use and how soon you can have a first build ready.
