Is there a program/application that will easily allow me to update my site frequently?

EDIT: I have already set up my website, so using a cms isn't really an option.

Is there something that that is "rather" user friendly (as I do plan to use it quite often if there is such a thing) that will basically allow you to schedule a task of say, deleting the text "I am going camping tomorrow" and insert the text "I have gone camping" in between and the right after at a specific time. Of course the program would need to be able upload the file at that specific time as well. This program should also be able to insert a record into phpmyadmin at a specific time as well.

I was going to look into Cron, but my host does not provide it. Should I switch host, or is there an alternative? Is Cron even capabl开发者_开发问答e of the thing I just described? If so would it be too complex (or not worth going thru the process everytime)? Is there another easier/better/alternative solution?

All inputs would be greatly appreciated, thanks!

Sounds like you need a CMS, maybe like wordpress. You can schedule an item to publish in the future.

Why not just point to a user's Twitter account and use that? Or a GMail Calendar if you want to schedule it? I'm assuming that you're using something like WordPress - which has plugins as I've described to do this task.
