CSV Editor plugin with file name change

Hi,

I create a plugin to edit csv file:

<?php
    /*
    Plugin Name: Editeur csv
    Plugin URI: http://www.eif-fel.com
    Description: Editeur csv
    Author: F. Leroux
    Version: 1.0
    Author URI: http://www.eif-fel.com
    */
	/** Step 2 (from text above). */
add_action( 'admin_menu', 'my_plugin_menu' );

/** Step 1. */
function my_plugin_menu() {
	add_options_page( 'Editeur CSV fête membres MAPP', 'Editeur CSV fête membres MAPP', 'manage_options', 'csveditor', 'csveditor' );
}
include("class.CSVHandler.php");function csveditor() {
$data=new CSVHandler(get_template_directory()."/fete.csv",";","record");
$data->Edit();
}
?>

How to put an button to change csv file name? And all my accent are replace by question mark.

Thanks
