I'm 15 years old and just getting started with microcontrollers. All of the commercial programmers are outside of my budget. There seem to be tons of cheap programmers that you can build for PICs on AVRs, but I cant seem to find any for the HC08. Are there any?

If you choose the HC08 family, you need only a serial-port, a MAX232 some diodes and Rs to create the interface.

If you want, i can mail a schematics with a programmer/debuger interface to you. Otherwise you can find the description in the datasheets.

Do I need any special software to program that? Codewarrior has ISP support, right?

The schematics i sent is a little bit sofisticated! But very functional.
You do not need additional software. Simply choose the ICD target from PE when you create a project. Then choose Class 1 ICS .... (Power controlled via DTR). Select a serial port and 9600 baud.
You have to set the right jumpers (see the pdf i sent) for the micro choosen!
Attention switch OFF the FIFO's for the serial port you want to use, otherwise the bock transfers will not work!
Sorry for the german doc (pdf), ti is unfinished so there are the jumper settings for the AB32 only.
