Hi Akshata,

I found in the apex:commandButton tag developer documentation that there is something called as ondblclick this calls the function when the button is clicked twice, one possibility is to show an alert message when ondblclick fires.

I hope this as helpful in your implementation and in case if it helped can you please choose this as the best answer so that it can be used by others in the future.
