Build me a simple Windows desktop gacha simulator for Deresute style pulls.

I want a clean app where I can click to do a pull, see the result on screen, and keep track of what I’ve gotten so far. It should feel like a small fan made Windows utility, easy to use, with a basic layout and clear buttons and counters. If it makes sense, add a few settings for things like pull count or simple rates, but keep it straightforward and fun.

Please make it work nicely as a Windows Forms app, and keep the code organized so I can open it in Visual Studio and run it without extra hassle. If you need to look up anything current, go ahead and check the docs online.
