Can't Code and Broke

Build Your Own Windows & Mac App with AI and $0

You have an idea for a Windows application.

You don't know how to program, and you don't want to learn. You don't want to pay someone else to build it either.

Once upon a time, you would have been stopped right there. In the time we live in now, you don't have to be.

I'm Keith Mullins. I'm not a programmer — I'm a retired engineering designer, a published author, and a self-taught cook who builds things with AI. I wrote a book called Can't Code and Broke that teaches non-programmers how to build real Windows and Mac applications using AI with $0 invested. This post is the short version of how it starts.

The most important thing you'll learn isn't programming

It's a process: a direct, to-the-point way of thinking about and explaining what you want.

Here's the mistake most people make. They open an AI chat and type something like:

"Build me a Windows application that keeps track of my customers."

That sounds perfectly clear to you, because you already know what you mean.

AI doesn't.

What information do you want to keep about your customers? Names? Addresses? Phone numbers? Email addresses? Purchase history? The AI will guess — and it will guess wrong. Then you'll be irritated at the AI for something that was your fault for not being specific.

Never assume. Verify.

That's the one rule. Apply it to every stage of the build.

Before you tell AI anything, you turn your idea into something buildable: you write down exactly what the app does, screen by screen, button by button. Then you set up a free workspace. Then you learn how to talk to the AI — not like a programmer, like a person giving clear instructions.

You'll test what the AI creates instead of assuming it works. When something breaks, you'll learn how to describe the problem precisely and feed it back. You'll repeat that process until your idea isn't just an idea anymore.

It becomes working software you can install and run.

It doesn't need to be complicated

The application you build doesn't need to be the next big thing. That's not the point. The point is to learn a process that works — one you can use again on the next idea, and the one after that.

I know this works because I've done it. I went from zero programming to real working software, and I did it without spending a dime.

If you want the full walkthrough — all eleven sections, from turning your idea into something buildable to building a Mac version without owning a Mac — that's what the book is for.

But the core of it is right here: be specific, test everything, and never assume. Verify.
