Text format inside GUI elements

I want to make a chat window, much like wow chat. For that i need to be able to:

• individually format (color) pieces of text inside the gui element who display the text.
• create links, clickable areas maybe

I've started the code with a GUILayout.Label but it doesn't seems to be the element I need. I guess i need something like an html gui element to achieve this but i do not know wich one (if there is one).
Any idea is appreciated.

 

This help?

Code (csharp):

1.  
2.  
3. function OnGUI() {
4.  
5.     GUI.contentColor = Color.yellow;
6.     GUILayout.Label("this text is yellow");
7.  
8.     GUI.contentColor = Color.red;
9.     GUILayout.Label("this text is red");
10.    
11.     GUI.contentColor = Color.white;
12.     GUI.backgroundColor = Color.blue;
13.    
14.     if( GUILayout.Button("this is a blue button with white text")   ){
15.    
16.    
17.         print("the button has been clicked");
18.    
19.    
20.     }
21.    
22.     GUI.backgroundColor = Color.white;
23.    
24. }
25.
