Query Table Present Result In A Form

I have a form that contains 3 text boxes, 1 Combo Box and a Command Button

txtLastName
txtFirstName
txtDOB
cboGender
cmdFind

I want the user to be able to enter at least one of these criteria and
for a form to pop up with a list of individuals that match the criteria

example

user enters Male under cboGender and Young in txtLastName
a Form will pop-up that will give a list of user that match those criteria


LastName, FirstName, DOB and Gender data are stored in tblPatientDemo


Any ideas on how I can accomplish this goal??
