No, the Import PDF feature allows you to save a new version of your PDF form that has a "Submit" button that submits the data back to FormsCentral which is available for you to view, analyze and manage on the View Responses tab. It does not provide a "web" version of the form.
In order to make the PDF form available online you will want to create a link to download the PDF and instruct users to fill it out using the free Adobe Reader (or Acrobat), you do not want to allow the PDF to be opened inside of a web browser as that will not work for most users. The FormsCentral PDFs must be filled out using Adobe Reader/Acrobat. Here is an FAQ on PDF in a web browser: http://forums.adobe.com/docs/DOC-4142
