Here's how you could use FindWindow to retrieve the handle to a window given its title:

class Program
{
    [DllImport("user32.dll", SetLastError = true)]
    static extern IntPtr FindWindow(string lpClassName, string lpWindowName);

    static void Main(string[] args)
    {
        var hWnd = FindWindow(null, "Untitled - Notepad");
        if (hWnd != IntPtr.Zero)
        {
            Console.WriteLine("window found");
        }
        else
        {
            Console.WriteLine("No window with given title has been found");
        }
    }
}
