Convert Excel spreadsheet into standalone Windows app

We have a Excel spreadsheet and we need the functionality turned into a standalone Windows app. The spreadsheet features: * a macro that grabs stockmarket numerical data from a text file on our website * uses standard Excel expressions such as IF, AND, OR, OFFSET, SUM, COUNTIF, INDIRECT * currently uses a Technical Analysis indicator called "Acceleration" which is provided by the AnalyzerXL Excel plugin. This is described as "Acceleration of changes calculated on current velocity of changes and a velocity of changes n periods before". This will need to be coded from scratch for the app. * a small amount of graphics and text that changes colour according to certain values (see screenshot) I need some kind of copy-protection scheme also. I would prefer a serial number that is locked to the VolumeID of the PC, but am open to other suggestions.
