Remove lists, Pages,usercontrols when solution retracting programitically

I have created one solution which create pages , lists, adds some usercontrols in layouts folders, when I deploy (WSP) solution package using central admin. All works fine .

Now the same should be happened vise versa. Whenever I will retract the same (WSP) solution using central admin , its should be remove pages , lists , usercontrol from the sharepoint application programitically .

Could you please tell me how to achive this ? Will be appreciate if someone help me out in this.
