Hi friends, I want to know what should be the trace width for 1A and 2A @ 230VAC supply, whether i can follow the same trace width as DC

I think there is no downside to using the same track width as DC. Keep in mind that at much higher frequencies, skin depth can become a factor however I doubt there are any skin concerns at 50 or 60 hertz.
Voltage tends to not be a factor in track width but is a factor in clearance/creepage requirements. I think that for creepage, IEC and UL standards (like 60950) use RMS working voltages, however you can use peak voltage as a safety margin for calculations.
