You can do it this way.
Add a new profile field (Single-Selection Radio Buttons)
---------------------------------------------
Title: Buttons/Text
Description: Select Yes to use buttons. Choose No to use text.

Options:
Yes
No
---------------------------------------------

You can leave everything else the same.

In the template of the custom page add

PHP Code:

<if condition="$bbuserinfo[fieldXX] == 'Yes'">
Button goes here
<else />
text goes here
</if> 


Replace XX with the field number
