You can Have Opera open more than one web page when you start the browser up. Simply right-click on the Opera Desktop icon and select 'Properties'. In the text box that shows what the shortcut leads to, add the web pages you want to load at the end of the line. Example:
Target: "C:\Program Files\Opera\Opera.exe" "http://www.wintipsinc.tk/" "http://www.google.com"
