PHP dev for next and Previous entries

Hi all,
I’m not a developer far from it but I am trying desperately to change the “next” and “previous entries” links at the bottom of the page into a:

< 1|2|3|4|5 > type of menu…

I can’t find a plugin that does this anywhere… Has anyone got an idea how to develop this?
A big (virtual 🙂 kiss to whoever can come up with it!
