Good Day
You can do this. I would suggest that you get a copy of "Integrating and Extending BIRT" (ISBN-10: 0321772822)as there is a chapter on Programming Using the BIRT Reporting APIs and they cover how to access report parameters.

Also take a look at the following:
http://help.eclipse.org/indigo/index.jsp?topic=/org.eclipse.birt.doc.isv/engine/api/org/eclipse/birt/report/engine/api/package-summary.html

From the above link:
A report engine supports running several types of task. Examples are GetParameterDefinitionTask, RunAndRenderReportTask, etc. To run and render a report, the following steps may be involved:
? The report design is opened by calling the ReportEngine.openReportDesign(...) The method returns an IReportRunnable object.
? With the IReportRunnable object, call ReportEngine.createGetParameterDefinitionTask(...) to obtain an IGetParameterDefinitionTask object, from which parameter definitions are retrieved. A UI page can be constructed based on the definitions to prompt end users for parameter values.
? An IRunReportTask object can be obtained by calling ReportEngine.createRunAndRenderReportTask(...). From the task, report parameters are set. Running options can also be set.
? The run() method on IRunAndRenderReportTask is called.



You can also take a look at the folowing DevShare to see if that may help you.
