Now I have to make a small utility that would download the

I have no internet related programming experience till now.
Are there any resources available for a beginner for developing such
a utility.
How should I proceed?
The 1990s are over, almost nobody cares about executable smallness
anymore, and the few that do care will use some program to strip out
the architectures they're not using. So I wouldn't worry about this
unless you get customer complaints about the application size.
Also how to know if a particular mac would be able to run a 64-bit
app? Some earlier Macs like PowerPC G4 could run Leopard but are not
able to run 64-bit apps.
Use sysctlbyname() with the key "hw.cpu64bit_capable". If the key
value is set to 1, then it's able; if it's undefined or set to 0, then
it isn't.
