Probably not, since you can't really make a spreadsheet-like widget unless you endeavor to make it an Excel clone. Many grid (table) widgets support edit-in-place, but that's as far as most of them go. The target userbase for full-featured spreadsheets is going to be users whom I'd presume already have access to Excel (edit: and/or access to a compatible product, like Google's online version or maybe one of the FOSS MSO replacements).
