Simple block-protection plugin

Hello,
can anyone write (and mostly important compile, because I can't do it, otherwise I would have also written the plugin itself) a simple plugin which listens for block breaking and block placing events and cancels them if the Player is not OP?
I need it because of the fact that a player in adventure mode is still able to break transparent blocks, and allowing a Player in my server to do this means that he can break vital parts of the map
I know I could do this with existing plugin, but I'm doing this request because a simple ad-hoc plugin would be much much faster.
I need it for Bukkit-1.4.6-R0.3.

Thank you very much!

EDIT: and maybe a /food command which gives the player 5 red apples? (in the same plugin)

Thanks

EDIT 2: I've written the plugin, can anyone compile it for me?
plugin.yml:

Code:

name: TFHelper
main: eu.th3game.tfhelper.TFHelperMainClass
version: 0.0.1
 
commands:
    food:
        description: This command give 3 apples.
        usage: /food

TFHelperMainClass.java:

PHP:

package eu.th3game.tfhelper;
 
import org.bukkit.plugin.java.JavaPlugin;
import org.bukkit.event.Listener;
import org.bukkit.command.CommandSender;
import org.bukkit.command.Command;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.EventPriority;
import org.bukkit.event.block.BlockBreakEvent;
import org.bukkit.event.block.BlockPlaceEvent;
 
public final class TFHelperMainClass extends JavaPlugin implements Listener {
    @Override
    public void onEnable() {
        getServer().getPluginManager().registerEvents(this, this);
    }
   
    public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
        if (cmd.getName().equalsIgnoreCase("food")) {
            if (sender instanceof Player) {
                ((Player)sender).getInventory().addItem(new ItemStack(260, 3));
            }
            return true;
        }
        return false;
    }
   
    @EventHandler(priority = EventPriority.MONITOR)
    public void onBlockBreakEvent(BlockBreakEvent e) {
        if (!e.getPlayer().isOp()) {
            e.setCancelled(true);
        }
    }
   
    @EventHandler(priority = EventPriority.MONITOR)
    public void onBlockPlaceEvent(BlockPlaceEvent e) {
        if (!e.getPlayer().isOp()) {
            e.setCancelled(true);
        }
    }
}


I've written the code with Notepad, so if I've forgot to import anything, please do it for me

 

If you have permissionsEX, this can block it anyway's I believe.

 

I don't have permissionsEX, and it couldn't help me with the food thing anyway.
I've written the plugin by myself, now I only need someone who can compile it for me, because I don't have my PC at the moment and I can't install anything on this one...

Sorry if I bump this, but I need is urgently

Nice code, you only missed the itemstack import
