Hi,
I'm an electronics newbie and for my application it would be very helpful if I could design a circuit just from DC batteries and resistors that would output a sin wave (AC). I don't know if this is possible. Is there any circuit design software where I could specify that this is what I want and have it try and create it?
Not quite. For an AC sine wave, you need AC batteries. DC batteries can only produce a DC sine wave.

Actually, it sounds like you're still working on basic electricity.
You're a long way off from understanding what is required. It appears you haven't even gotten thru Page 12 yet.
No, not from DC batteries and resistors.... first you have to understand what a DC battery is and what a resistor is... A DC battery outputs a steady current (Direct Current) when you connect it to a resistor, and it also produces a Voltage across the resistor you connect it to, a typical AA battery will cause 1.5 Volts across your resistor... A resistor resists current flow and causes a voltage drop, (a current to voltage converter?) and the linear equation V =3D I*R describes the relationship between voltage and resistance... if you understand this then you will see why you can not create an alternating current source from only resistors and a battery.
