Initial term of field expression must be a concrete SObject

Quote__c is lookup in SSOW__c. I am trying to get a id for a visualforce page. My code is paste below and this the error it is throwing

This is the part of the code. I defined SSOW intially in my code as


Error: Compile Error: Initial term of field expression must be a concrete SObject: LIST<SSOW__c>


public List<SSOW__c>SSOWs{get; set;}

public PageReference genSSOW() {
     SSOWs=[select Id from SSOW__c where Quote__c =:quote.Id Limit 1];
        PageReference ssowPage= new PageReference('/apex/Smartsow?Id=' +SSOWs.Id);
        return SSOWPage;



Try this in your code

PageReference ssowPage= new PageReference('/apex/Smartsow?Id=' +SSOWs[0].Id);


Its give me this error 

System.ListException: List index out of bounds: 0
