Sketch a part with user input macros

Hello all I am new to solidworks macros and I was wondering if there was a way someone could give me some helpful tips on how to make a macro so a user could click the macro button and have it come up with an input box to enter in values for the specified dimensions of the part as in, Radius, Thickness, and other dimensions. 

Thank you,
