How to Create Visualforce Related List with Edit and Delete Action's?

I have requirement of create a Visualforce Related List to display opportunity Details in Contact object with Edit and Delete Actions.

Page:- 

<apex:page standardController="Contact" extensions="sampleDetailPagecon">

<style>

.fewerMore { display: none;}

</style>

 <apex:form >

 <apex:pageMessages />

 <apex:detail relatedList="true"></apex:detail>

 <apex:pageblock id="CustomList" title="Related Opportunities">

 <apex:pageblocktable value="{!oppz}" var="o" rendered="{!NOT(ISNULL(oppz))}">

  <apex:column >

             <apex:facet name="header">Action</apex:facet>

                        

  <apex:commandLink action="{!editOpp}" value="Edit">

  <apex:param name="oppid" value="{!o.id}"/>

 </apex:commandLink> &nbsp; | &nbsp;   <apex:commandLink action="{!deleteOpp}" value="Delete">

  <apex:param name="oppid" value="{!o.id}"/>

 </apex:commandLink>

 </apex:column>

 <!-- 

 <apex:column >

   <apex:commandLink action="{!deleteOpp}" value="Delete">

  <apex:param name="oppid" value="{!o.id}"/>

 </apex:commandLink>

 </apex:column>

 -->

 <apex:column value="{!o.Name}"/>

 <apex:column value="{!o.Account.Name}"/>

 <apex:column value="{!o.Type}"/>

    <apex:column value="{!o.CloseDate}"/>    

 </apex:pageblocktable>

 </apex:pageblock>

 </apex:form>

  <apex:relatedList list="Opportunities" />

</apex:page> 

Controller Class :-

public class sampleDetailPagecon {

private List<Opportunity> oppz;

private Contact cntact;

public sampleDetailPageCon(ApexPages.StandardController controller) {

 this.cntact=(Contact)controller.getRecord();

 }

 public List<Opportunity> getOppz()

 {

     Contact con = [Select id, Account.id FROM Contact where id =:cntact.id];

     if(con.Account==null)

     return null;

     oppz = [Select id, Name, Account.Name, CloseDate, Amount, Type from Opportunity where Account.id =: con.Account.Id];

     return oppz;

 }

 public Pagereference editOpp()

 {

     String oppid= ApexPages.currentPage().getParameters().get('oppid'); 

     

    return new PageReference('/006/e?id='+oppid+'&retURL=/006/');

 }

  public Pagereference deleteOpp()

 {

     String oppid= ApexPages.currentPage().getParameters().get('oppid'); 

     

     Opportunity opp = [Select id from Opportunity where id =:oppid limit 1];

     if(opp !=null && opp.id !=null){

      delete opp;

     }

    return null;

 }

}

once this is done you need to add the Visualforce section in Contact object with Edit page layout and add this visualforce section in contact related list.
