Hi sreeram ,
   go through the example below.

apex class:

public class disableInputField1 {

    public Opportunity opp {get; set;}
    public Boolean disableInput {get; set;}

    public disableInputField1 (){
        opp = new Opportunity();
    }

    public void disableCloseDateInput(){
        disableInput = true;
    }

    public void enableCloseDateInput(){
        disableInput = false;
    }
}


visualforce page:

<apex:page controller="disableInputField1">
    <apex:form >
        <apex:commandButton value="Disable inputField" action="{!disableCloseDateInput}" rerender="oppName"/>
        <apex:commandButton value="Enable inputField" action="{!enableCloseDateInput}" rerender="oppName"/><br/><br/>

        Opportunity Name:&#37;
        <apex:outputPanel id="oppName">
            <apex:inputField value="{!opp.CloseDate}" id="oppNameInput" required="false"/>
        
            <script>document.getElementById('{!$Component.oppNameInput}').disabled = {!disableInput}; </script>
        </apex:outputPanel>
    </apex:form>
</apex:page>

Note :we can also disable input fields by using styles.
for example document.getElementById('elementid').style.display='none';

if this provides you with useful information and if this is what you where looking for then please mark it as a solution for other benefits.

Disable in sense, Do you want to null the fields or you do not want to show them on the VF Page?

Hi Srikanth,

I want to show them in the Visual Force page but just like a ready only text field which is greyed out. Thanks in advance

I would use the <apex:outputField> tag. Like below:

<apex:outputField value="{!yourObject__c.yourField__c}"/>

Generally for something this lightweight you should keep it client-side. I woul go with a Javascript function (you can use a command button or a vanilla HTML button) but just call a javascript function that sets your targetted elements with a property of disabled.
