Need to create new vf page with custom controller

I was having one custom button with JS code as below: 
{!requireScript("/soap/ajax/30.0/connection.js")}
{!requireScript("/soap/ajax/30.0/apex.js")}

var opp = new sforce.SObject("Opportunity");
opp.id = "{!Opportunity.Id}";

try {

opp.isStatus = true;

var optresult = sforce.connection.update([opp]);
if(optresult[0].success=='false') {
alert(optresult[0].errors.message);
} else {

sforce.apex.execute('populateOpportunity', 'automatePopulatingOpp', {optyId:'{!Opportunity.Id}', action:'Default'});

alert('{!$Label.SuccessMsg}');
}
} catch(err) {
alert(err.message);
}
document.location = '/{!Opportunity.Id}';

I'm new to vf page implementation. I need to replace this JS with Vf page. I've written below vf page and custom controller.

VF Page 
<apex:page standardController="Opportunity"  showHeader="false" extensions="oppController" >   
    <head>
        <style type='text/css'>
            .popupBackground{
            left: 20%;
            color:red;
            position: fixed;
            width: 450px;
            height: 100px;
            margin-left: -200px;
            top: 50px;
            }
            .popupBackground .close{
            position: absolute;
            background:#008CBA;
            color: white;
            bottom: 0;
            right: 10px;
            font-size: 10px;
            text-decoration: none;
            width:50px;
            }
        </style>
    </head>
    
    <apex:form rendered="{!showSuccessMsg}" id="opp">
        <apex:pageMessages id="errmsg"></apex:pageMessages> 
        <body onload="init();">
            <apex:outputPanel styleClass="popupBackground"  >
                <center>
                    <apex:outputText value="{!$Label.SuccessMsg}" escape="false"/>
                    <apex:commandButton value="OK" styleClass="close" onclick="parent.window.close();"/>
                </center>
            </apex:outputPanel>
        </body>
    </apex:form> 
</apex:page>

Custom Controller 
public class oppController {
    public Id oppId;
    public Boolean showSuccessMsg{get;set;}
    public Boolean showErrorMsg{get;set;}
    
    public opptController(){
        showSuccessMsg = true;
        showErrorMsg = false;
        
        if(oppId != NULL){
            Opportunity opp = new Opportunity(Id = oppId);
            opp.isStatus = true;
            try{
                update opp;
                populateOpportunity.automatePopulatingOpp(oppId,'Default');
                showSuccessMsg = true;
                showErrorMsg = false;
                Error.LogSuccess(Label.SuccessMsg);
            }catch(Exception e){
                showSuccessMsg = false;
                showErrorMsg = true;
                Error.LogException(e);
            }
            showSuccessMsg = true;
            showErrorMsg = false;
            Error.LogSuccess(Label.SuccessMsg);
        }        
    }
}

Can anyone please help me out to correct this?

Hi Sridhar,

Thanks for your reply.
It's working only for success. But there is no scenarios for failure. How will it handle failure here?

Thanks!

Allen
