Forms & Retrieving Data From .JSP

[OTTO]

Hey everyone, So I am trying to develop a calendar that can be edited by anyone. I know this can be done with PHP, however I am very limited in the fact the website I am working on is modified through a GUI. I do not have access to the back end. I can however use HTML and upload some files. So I am curious if I design a Calendar using HTML would there be a way for me to update it with information users input via a form? Thanks in advance.
