Is there a way to get an embedded version of Gmail / Google Calendar with login?(like the one on iGoogle)  I did find how to embed a calendar... but I want to see my very own calendar.(Writing an own start page.)
Integrate Gmail and Google Calendar with login
gmail;google;google calendar;embed
You can only embed one calendar in a gadget at once, so unless all your events in your Google Calendar is under one single calendar, or else it is not going to be possible.You can experiment with <iframe>, though it is a rather old and hacky way to get things working.
