Very Simple Ajax Task - Display Popup with php page after form submit

Hello, This is an extremely easy task and shouldn't take more then a few minutes to accomplish, therefore the budget I allocate for this is only $10. I basically have a form with some post fields sent as php variables. All I need is that after the form is submitted it will open an Ajax Popup with a php page that will assume the same post fields used in this form. The post fields are already used for something else, but since the popup with the php will be displayed in the same page it should automatically inherit the variables from the form. Need this done quickly Thanks
