I'm going to try this one out this evening when i get home... I'll report back if i succeed.
I created an altcoin for home use (getting my kid interested in crypto coins, and having an alternative "payment" method when she helps us out around the house).
Creating a coin, building the linux deamon and the linux QT wallet just took me a couple of hours. I gave up compiling the windows QT wallet after a couple days trying. Maybe this tutorial will work
