btnClick.Attributes.Add("onclick", "window.open('GiftWindow.aspx');");
Should be something like this, I work in VB.net mostly.

Couple of ways this can be done. The easiest is as xakem suggests, though I would recommend changing the type to "button" not "submit" (it might not make a difference functionally, but it's better formed code).

So, if you want to open a new window with the hyperlink "my_web_page.html" then the code is:
<input type="button" value="CLICK FOR NEW WINDOW" onClick="window.open('my_web_page.html')">

Note that whatever you set the "value" parameter to will be the text the button displays.

If you need more control over the window that will open (for example, you want to set the window to a specific size), you might use a little JavaScript to make it easier:

First, you have to define your "window opening function" using JavaScript, so put this in-between the <head></head> tags of your web page. If you don't have <head></head> tags, better start using them! And you're not forgetting your <title></title> tags right?

<html>
<head>
  <title>My Web Page Title</title>
  <script type="text/javascript" language="javascript">
    function openNewWindow(whichURL) {
       config='toolbar=no,location=no,directories=no,status=no,menubar=no,width=385,height=290,scrollbars=no,resizable=yes';
       window.open (whichURL, "myNewWindow", config);
      }
    </script>
</head>
<body>
 some stuff.....
  <p>Click here for a   new window <input type="button" value="CLICK ME" onClick="openNewWindow('my_web_page.html')"></p>
</body>
</html>

So what's going on in the JavaScript function? Well, a couple of cool things.
1 cool thing is the config parameter which lets you control all sorts of attributes of your new window, like whether the user can resize it, whether there are scrollbars, what the size is.
Another cool thing is that you can re-use this function for any url. when you call the function using onClick="openNewWindow()" just put the URL inside the brackets (don't forget to use single quotes).

Hope this gives you some options.
