Rashmi, you are trying to implement a client side logic, and doing a server side coding using controller will NOT help.

Best way to achieve this is through javascript. Take a look at the below extract of your code. I have updated it with javascript logic using jQuery:
  
<script>
	function disableAllVFButtons() {
		var jnc = jQuery.noConflict();
		
		jnc(".cvf_button").each(function(argIndex, argEle) {
			jnc(this).prop('disabled', true);
		});
	}
</script>
<apex:pageBlockButtons >
	<apex:commandButton action="{!cancel}" value="Cancel" styleClass="cvf_button" onclick="disableAllVFButtons();" />
	<apex:commandButton value="Convert" action="{!convertLeadFunction}" onclick="disableAllVFButtons();" reRender="pgblk" styleClass="cvf_button" />
</apex:pageBlockButtons>

The summary of the fix is as follows:
1. Set a styeclass to each of the buttons so that it provides a handle for accessing them from within javascript/jQuery.
2. Write a javascript function to handle button disable operation.
3. In each of the buttons, onclick invoke the javascript function.

Do note that the code is draft and I haven't tried compiling/running. But I certainly hope it guides you in the right direction.

Rashmi Khanna,

Hey i wrote some code to disable the button on the onclick event using the boolean variable and here is the snippet.

Please let me know if you need any other help.
  
public with sharing class disableButtons {
    public boolean diableButttonFlag{get;set;}
    
    public disableButtons(){
       diableButttonFlag = false; 
    }
    

    public void disableButton() {
        diableButttonFlag = true;
        try
        {
            //diableButttonFlag = false;
        }
        catch(exception e){
            
        }
    }
}
  
<apex:page controller="disableButtons">
    <apex:form >
        <apex:pageBlock id="block">
            <apex:pageBlockButtons >
                <apex:commandButton disabled="{!diableButttonFlag}" value="save" action="{!disableButton}" reRender="block"/>
            </apex:pageBlockButtons>
        </apex:pageBlock>
    </apex:form>
</apex:page>


Thanks,
pRAMODH.

See if this works: 
function disableAllVFButtons() {
		var jnc = jQuery.noConflict();
		
		jnc(".cvf_button").each(function(argIndex, argEle) {
			jnc(this).prop('disabled', true);
			jnc(this).prop('value', 'Please Wait While Converting');
		});
	}

There is a new entry at line 6 to show user message.
