Grzegorz,

This is a simplest form of SharePoint 2010 Modal Dialog, using SP.Dialog class!

function test() { 
        //debugger; 
        SP.UI.ModalDialog.showModalDialog({ 
            url: "/Lists/Announcements/NewForm.aspx", 
            title: "Add item", 
            allowMaximize: true, 
            showClose: true, 
            width: 800, 
            height: 600, 
           dialogReturnValueCallback: silentCallback 
       }); 
   }; 

   function silentCallback(dialogResult, returnValue) { 
   } 

   function refreshCallback(dialogResult, returnValue) { 
       SP.UI.ModalDialog.RefreshPage(SP.UI.DialogResult.OK); 
   }

This is same dialog which opens when you add new item to a list, or edit any item! You can provide any url in SP Dialog Options!

Try this:

LiteralControl controlLit = new LiteralControl();
controlLit.Text = "<a onclick='javascript:test();' href='#'>click here</a>";
 e.Cell.Controls.Add(controlLit);
