Options for a customized contact list I downloaded...

[Sponge14]

I downloaded this program that seems to be what I am wanting out of a contact list...
www(dot)freewarepp(dot)com(/)utilities(/)contactmanager(dot)shtml
(Sorry about typing the address like that, the spam filter wont let me post any other way)

What I want to know is how can I get the "Contacts" softkey to run this program instead of the Msoft Contact list?

I should say first... To run the new contact manager, you have to navigate to the directory it's stored at and double click the .exe. That is obviously not efficiant. I would like to replace the Contacts softkey, as that would be the best solution; if that is not possible, then how can I put my own icons on the Today screen, that would run this program?
