Just to give a hint as to how to go about it, I define the xkcoor and ykcoor lists as a sequence of consecutive integers:
In[1]:= xkcoor=Table[j,{j,1,4}]Out[1]= {1,2,3,4}
In[2]:= ykcoor=Table[j,{j,1,4}]Out[2]= {1,2,3,4}
Then you can use
In[3]:= Partition[Flatten[Table[{xkcoor[[j]],ykcoor[[i]]},{i,1,3},{j,1,Length[xkcoor]}]],2]
Out[3]= {{1,1},{2,1},{3,1},{4,1},{1,2},{2,2},{3,2},{4,2},{1,3},{2,3},{3,3},{4,3}}
