Hello, have a look here: https://github.com/apogio/old-school-bitcoin. It generates a private key along with its public key and its legacy address. It also provides you with the corresponding QR codes. It is not a brainwallet checker, but you could use ideas from this in order to develop what you asked.
Before you check it out though, please consider:
1. It's in Java.
2. Don't rely on this kind of programs (even though I am the one who developed it). Please make sure to use well maintained software wallets.
3. I think I will develop what you asked, just for fun. I will let you know.

This could be written in one class in one file.
I rarely used Java.
Need some C/C++/C# solution.
