Car will start but won't move when I give it gas?

I was merging onto the highway and started to accelerate fairly quickly. I got up to about 110/120 kmph and then my car started to slow down while my foot was on the gas, my check engine light soon, parking break and windshield fluid light all came on also. I pulled over to the shoulder and attempted to restart the car, it would start but when I shifted into drive I could not give the car any gas and it wouldn't move. Any idea what problem it could be? I drive a 2003 Nissan Altima with around 210k clicks on it. I hope it's not the transmission but if it is how much would it cost me?
