Question : How do I create a speciallized web browser

Fellow Experts:

I am at the conceptual stage in thinking of a specialized web browser or widget, similar in concept to an RSS reader or the Weatherbug desktop application.  It would need to be minimally configurable, something that could disappear into the system tray and run in the background.  It would have access to only one web service.  I'm fairly clear on the web service side of things, but have never written a desktop or mobile app.

The user experience I want to produce is a simple download and install.  The little program will start automatically and run with as little fanfare as possible.  When the little program detects a state change on the web service, it will pop up a notice or change color or ring a bell - somewhat similar to what the Weatherbug does when there is a severe weather alert.

What kind of work or expense I in for when I embark on this project?  What are some good learning resources and examples I can look to for guidance?

Thanks to all, ~Ray

>> my question is if you use m32 flag, is there a limitation of the ram that you can use

Since the address space becomes 32 bit the maximum memory a 32 bit process can possible address is 4GB. That said, in reality the amount of user memory is a lot less (usually 1 or 2 GB) since the rest is reserve in the processes memory map for various other reasons (such as for use my the kernel to map devices - this is probably a poor example).
