Gnucash/gnucash — reverse-engineered prompt

Build me a personal and small business accounting program similar to GnuCash. I want a desktop app where I can create an accounting file, set up accounts like checking, cash, income, expenses, assets, liabilities, and equity, then enter transactions using proper double entry so money always balances.

It should let me open and save account files, start from a sample file, import Quicken QIF files, and show useful views for accounts, registers, balances, and basic reports. Please include support for multiple currencies and a way to fetch online stock or currency prices if the needed tools are installed.

Make it usable for normal people, with clear menus for opening files, importing, editing accounts, and viewing help. It should respect the computer locale for language and number formats when possible. Use a solid native desktop approach and look up the current build and platform docs online if you need to.
