Build me an application to generate pages for a WordPress site

High level project overview I’m running a WordPress site and I want an application thatwill allow me to generate pages that are dynamically built off of a set oftemplates. The templates should be able to accommodate static and dynamic(changes as a function of a few variables) text and to display chart files (giffiles created from Excel and saved in a folder). I should be able to easilyupload the output of the application into my WordPress site (e.g., ftp).
