Scratch

^exe "converters" merely package Scratch with the respective project. Does the job, but I believe calling it a "converter" is quite misleading 

You could theoretically apply whatever proprietary license you wish to your project, as long as you don't upload it to the website. Uploading it to the Scratch website automatically applies the Creative Commons Attribution-Share Alike license, which permits people to make derivative works based in your project.

It's also important to know the licenses of Scratch and Squeak, as you'll be also distributing both of these with your project, provided you're using an .exe "converter". Luckily for you, both Scratch 1.4 and Squeak are under the MIT License, which basically lets you do whatever you want with the software, including distributing them along with a product you're selling (your project), as long as you include a copy of the exact same license. Portions of Squeak are also under the Apache license which seems to be equally liberal.

tl;dr: Yes, you can, but provide copies of the MIT and Apache licenses with your program, to avoid any possible legal hassles. You can license your project however you want, and even sell it.

Disclaimer: I'm not a lawyer or anything remotely close to one, but this question has been asked many times, and the answer is quite clear to me. Also, most users seem to think selling projects would go against the license of Scratch, or Squeak, but this is, apparently, not true, and I'd like to clear that up. If you can, ask an actual lawyer rather than kids in a forum
