If you've run Minecraft on your machine, then you do have a .minecraft folder. It can be a bit tricky to find. Here's an easy way to get to it:

Launch Minecraft.
Select "Options"
Select "Resource Packs..."
Select "Open resource pack folder"
Go up one level

To get to the .minecraft folder, you can always just open Run from the start menu and type %appdata%\.minecraft\, then click Run. It'll open your minecraft folder.
