Create web browser in my unity game

Hello I have a question. How can I create a small web browser in Unity 3D?, I mean, I want to open a small window as a web browser into my game, the game created can be an executable or web player.

For The webplayer you will have a bad time ,but for Standalone, there are some packages that use plugins (Unity Pro only and not available for the webplayer)
One of them is uWebKit

thank you
