first of all ids are not integers combain with character and numbers chouse as 
string id=[select id from bankapplication__c where account_number__c=:accnum];
this what you need to do
why beacuase you getting error 
IN soql you only search  with object field name only 




but you are trying to modify account balance so you do one thing 

bankapplication__c b=[select id,account_balance__c from bankapplication__c where account_number__c=:accnum];
b.account_balance__c=5000;
update b;

damount is the text field in the visualforce page 

 <h1>Account Holder Name</h1><apex:inputText id="dname" value="{!dname}"    />
