Hi Rabbani,

You can achieve this easily through Workflow (Task).

However, With Trigger  You can use this code: 
trigger OpportunityTask on Opportunity (before insert,before update){
 for( Opportunity opp:Trigger.new)
    {
        if(opp.StageName=='Closed Won')
        {
           task t=new task();
           t.whatid=opp.id;   
           t.subject='New Task' ; // You can put your own subject.
               insert t; 
    }

    }
}

Warm Regards,
Sourav.

Hi Rabbani,

You can use this code:

trigger testTrigger on Opportunity(before update, after insert){
 list<task> listToInsert = new list<task>();
 for(opportunity opp : trigger.new){
  if(opp.stageName == 'Closed Won'){
   task taskObject = new task();
   taskObject.whatId = opp.Id;
   taskObject.subject = 'test';
   listToInsert.add(taskObject);
  }
 }
 if(!listToInsert.isEmpty()){
  insert listToInsert;
 }
}


Hope this helps!
​Thanks

Hi,

You must go with Workflow Only. But also if you want trigger then pls refer below code: 
trigger OpportunityTask on Opportunity (before insert,before update){
List<Task> taskInsertList = new List<Task>();
 for( Opportunity opp:Trigger.new)
    {
        if(opp.StageName=='Closed Won' && (Trigger.isInsert || (Trigger.isUpdate && Trigger.OldMap != null && Trigger.oldMap.get(opp.Id).StageName != opp.StageName)))
    {
           task t=new task();
           t.whatid=opp.id;   
           t.subject='New Task' ; // You can put your own subject.
           taskInsertList.add(t); 
    }

if(!taskInsertList .isEmpty()) insert taskInsertList ;

    }
}
