 var username : String;
 var password : String;
 var table1 : boolean;
 var table2 : boolean;
 var window1 : Rect = Rect(20,20,500,500);

 function Start()
 {
 table1 = true;
 }

 function OnGUI()
 {
 if(table2 == true)
 {
 window1 = GUI.Window(0,window1,firstwindow,"LOGIN WINDOW");
 }
 if(table1 == true)
 {
 GUI.color = Color.green;
 GUI.Label(Rect(Screen.width*(2/6.55),Screen.height*(1.9/6.3),Screen.width* (1/6.55),Screen.height*(.6/6.3)),"USER");
 GUI.Label(Rect(Screen.width*(2/6.55),Screen.height*(2.5/6.3),Screen.width*(1/6.55),Screen.height*(.6/6.3)),"PASSWORD");
username = GUI.TextArea(Rect(Screen.width*(3/6.55),Screen.height*(1.9/6.3),Screen.width*(1.5/6.55),Screen.height*(.3/6.3)),username,15);
password = GUI.PasswordField(Rect(Screen.width*(3/6.55),Screen.height*(2.5/6.3),Screen.width*(1.5/6.55),Screen.height*(.2/6.3)),password,"*"[0],10);
if(GUI.Button(Rect(Screen.width*(2.5/6.55),Screen.height*(3.5/6.3),Screen.width*(0.5/6.55),Screen.height*(.4/6.3)),"OK"))
{
table2 = true;

This just an example, you can modify it to fit your needs.

function OnGUI() {
    GUI.Label(Rect(10, 10, 100, 20), "Username is: " + username);
    GUI.Label(Rect(10, 30, 100, 20), "Password is: " + password)
}
