Ethernet led controller?

Im looking to control things over the internet so i figured start with something simple like turning a led on and off. I've looked around on the form with not much success trying to figure out how to click a button on my arduino hosted webpage and turn a led on or off. Could someone show me some simple code to do this? I have some code that has a button that will just redirect you to google how can I make that button turn a led on or off?

#include <SPI.h>
#include <Ethernet.h>

byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
IPAddress ip(192,168,1, 177);

EthernetServer server(8081);

void setup()
{

Ethernet.begin(mac, ip);
server.begin();
Serial.begin(9600);
delay(50);
Serial.println("Server online!");
}

void loop()
{
// listen for incoming clients
EthernetClient client = server.available();
if (client) {
// an http request ends with a blank line
boolean currentLineIsBlank = true;
while (client.connected()) {
if (client.available()) {
char c = client.read();
// if you've gotten to the end of the line (received a newline
// character) and the line is blank, the http request has ended,
// so you can send a reply
if (c == '\n' && currentLineIsBlank) {
// send a standard http response header
client.println("HTTP/1.1 200 OK");
client.println("Content-Type: text/html");
client.println();

client.println("");
client.println("Arduino Website!");

client.println("<form method="link" action="http://www.google.com"> <input type="submit" value="Google"> ");
client.print("");
break;
}
if (c == '\n') {
// you're starting a new line
currentLineIsBlank = true;
}
else if (c != '\r') {
// you've gotten a character on the current line
currentLineIsBlank = false;
}
}
}
// give the web browser time to receive the data
delay(1);
// close the connection:
client.stop();
}
}

Some simple web page control code.

//zoomkat 12-8-11
//simple button GET code for controlling pin 4 and servo pin 6
//for use with IDE 1.0
//open serial monitor to see what the arduino receives
//use the \ slash to escape the " in the html 
//address will look like http://192.168.1.102:84 when submited
//for use with W5100 based ethernet shields

Thanks zoomkat that helps a ton!
