In which country? You're probably right though, that's what I'll end up doing

In the USA, you do not necessarily need a license to do business until you make over $600 per year. However, since this would just be supplemental income, there is really no need for legalities. You just claim it as 'other' income.
If outside of the US, not sure what is required. I doubt anyone will shoot you for selling 10 copies of your software. If you sell thousands, then open a business with the money.
The key is that if you have something people want (morally, ethically and legally) - sell it. If you wait, you WILL lose business (and probably have).
