GETFILE() is a good start, but it only allows you to choose a file. If you want to do this the quick way, just let your users select a file with getfile(), then use the shellexecute API to display it, and let windows decide how to what sort of file it is.

This is the syntax:

cFile = GETFILE()

declare integer ShellExecute in SHELL32.dll integer nWinHandle,string cOperation,string cFileName,string cParameters,string cDirectory,integer nShowWindow
if !EMPTY(cFile) AND FILE(cFile)
  ShellExecute(0,"OPEN",cFile,'',sys(2023),1)
endif

I hope this is what you were looking for.
