Standalone web calendar into mambo

[Fr3dY]

Hi there, I have a standalone web based calendar that i wish to put into mambo. I do not want to create a component but I just want to create a link to this web based calendar. If I use a wrapper, I will have to enter the url but instead of that, what I want to do is that create a simple page(simple.php) that have the url of this web based calendar as I do not want my users to log in twice. This is what I intend to do.

1. Create a menu called Calendar.
2. This menu will go to the page simple.php that contains the url of this web calendar.
3. Web calendar will be displayed in the mambo website.

My question is if I put my cursor at each of the menu in the user menu, for instance at the logout link, there will be option=com_login&Itemid=34. Where are the codes in which they perform the switch statement for this? In which page? Another question can this be done?

Thanksssss
