C# and MySQL

Question

Hi, i have a question whether this is smart or stupid move.
FIrst of all, im making a game using C# and MySQL where you have a simple battleground with 3 options to attack (head, chest or legs). My idea is to collect attack/defense info from the form every turn and write it in the MySQL table so i could read it form another computer. Two players who are fighting will have to have an account in the database so they could fight, obviously(doh). Is this smart? I dont have intentions of selling this or anything but just to improve my programming skills. 
The thing is, the more i think about it, it sounds worse. So if you know of any other method to collect needed info from one form and use it in another form on completely different computer i'd be grateful. Thanks
