Well i don't think there is a direct way you can open a page(pop up)with naked HTML!
you have to use one of these:
FLASH
JAVAscript
DHTML
there are other methods too but these are the most simple things you can use.
among these FLASH and javascript seem to be better,because most browser support them.
between FLASH and javascript FLASH is easer to handle.
