How to install a minecraft mod?

Okay I really want this mod called archimedes ship mod. I have minecraft 1.6.2 and really am kind of a noob with minecraft. Anyway how can I install this mod WITHOUT having to install minecraft forge? Thanks!

Added (1). Thanks! But when I look in the %appdata% I can't find a folder named ".bin"…

First find the 'minecraft.jar' file. Click the Start button, and type " %appdata% " into the search window (without quotation marks but with one space before and another after the typed string) to get to Windows' application data folder. The folder '.minecraft' will be at the top. Open the folder titled 'bin', and look for the file 'minecraft.jar'--this is where the magic happens.

When you find it, make a copy of 'minecraft.jar', and stash it somewhere. If something goes wrong, you'll want a clean copy to start over with. Right-click the original minecraft.jar, and open the archive with Win-RAR/7-Zip. You'll see a long list of files in a new window. Follow the instructions provided by the mod at this point: For the WW2 Guns mod, you'll copy all of the '.class' files from ModLoader, ModloaderMP, AudioMod, and the WW2 Guns mod into the open 'minecraft.jar' archive.

The last and most important step: Delete the 'META-INF' folder inside the 'minecraft.jar' file; otherwise, Minecraft will just crash when you start it up. Close the file when you're done.

And with that, you're set! This particular mod requires collecting materials, so if you want to see whether it worked, create a new world in Create mode, and spawn a few guns to see them in action.

If someone tell show you in a graphical way, then it could be better to install instead of orally or in a written. When someone provide in a written way, if they miss any of the steps, then possibly you will not able install it. It is better to check the site who provides Minicraft mod. In my knowledge, there's a resource, I hope possibly here you get all the general information by which you are looking for.
