The integers from 1 to 174, and 176, can be so expressed without the need for decimal point or factorial. 175 and 177 can't, though.
elias's answer shows expressions for some integers. In some cases their expression involved factorial or power; it turns out that many integers can be reached using only addition, subtraction and multiplication:
$11=3*4-2+1+0$;
$12=2*4+3+1+0$;
$13=3*4+2-1+0$;
$14=3*4+1*2+0$;
$15=3*4+2+1+0$;
$16=4*(3+2-1+0)$;
$17=3*(4+2)-1+0$;
$18=1*3*(4+2+0)$;
$19=3*(4+2)+1+0$;
$26=2*(3*4+1+0)$;
$27=3*(4*2+1+0)$;
$28=4*(2*3+1+0)$;
$30=2*3*(4+1+0)$;
$32=2*4*(3+1+0)$;
$36=3*(2+1+0)*4$;

Reaching some integers without factorial or decimal point entails using a power:
$89 = 3^4+10-2$;
$107 = 10^2+4+3$;
$130 = 2*(4^3+1+0)$;
$131 = 132-4^0$;

$161 = 2*3^4-1+0$;
$164 = 2*(3^4+1+0)$;
$165 = 13^2-4+0$;
$166 = 102+4^3$;
175 and 177 can be expressed by dint of using a decimal point, but cannot be obtained using just addition, subtraction, multiplication, division, powers and concatenation.
$175 = (34+1)/.2$;
$177 = (2+4-.1)*30$
Even if decimal point is allowed, 178 cannot be obtained.
