I want to develop something better than this: (http://soapcalc.net/calc/SoapCalcWP.asp) I am very new this and I figured I would start by trying to develop a UI. This will need to be able to be integrated for both desktop/laptop browser as well as mobile phone browser usage. Where should I start? What do you think the best language to code it in would be? (I was thinking either PHP or Javascript or a combination of both) thanks for any and all help/direction.
combination of both will be better.. as javascript is client side scripting and php is server side scripting.. so comibnation of both will make something good for you.
