Proposed Milestones
$500 USD - full solution
What database engine do you want to use? (MySQL, PostgreSQL, SQlite3, MSSQL, ...)
What do you exactly mean on "all Windows x32/64"? (Windows XP, Windows 7, Windows 8, Windows 10) I guess you will have problems if you want to create for example an XP compatible solution. So you should be more specific on this.
