java swing, disappearing frame/component is driving me nuts (code inside)

[mchammer187]

I wrote a applet but the all the button checkboxes and radio buttons and text fields just disappear on me when i run it

it is supposed to take in text from a JTextbox and have 2 check boxes for bold and italic and 3 radio buttons for size 14, 16, or 18

it works correctly except for the buttons either disapper or never show up but i can click where they are supposed to be and they work

any help would be appreciated
