I suspect this is the problem:

// Reformatted
PreparedStatement ps = con.prepareStatement(
    "INSERT into project(OPANo, CollegeName, ProjectName, SanctionNoDate, " + 
    "TotalOutlayInLakhs, ProjectDuration, AmountReleased, " + 
    "BalanceToBeReleased, PRSGsHeld, NextPRSGDue, CompletionMonth, Status) " + 
    "VALUES(?,?,?,?,?,?,?,?,?,?,?)");

Count the question marks, then count the number of values you're trying to specify...

(Then note that you're calling ps.setString(12, t13.getText()) - confirming that you really meant there to be 12 parameters, not 11...)
